Science & Technology / Governance

1. One Clock For India: Govt Mandates IST For Official & Commercial Use

Context

• The Union Consumer Affairs Ministry has notified the Legal Metrology (Indian Standard Time) Rules, 2026, establishing Indian Standard Time (IST) as the sole official time reference for India.
• The rules have been framed under Section 52 of the Legal Metrology Act, 2009.

Legal Metrology Act, 2009

• The Legal Metrology Act, 2009 is the principal legislation governing standards of weights and measures and matters associated with their use in India.
• It came into force in 2011, replacing the earlier Standards of Weights and Measures Act, 1976 and Standards of Weights and Measures (Enforcement) Act, 1985.
• Key provisions of the Act include standardisation, legal units based on the International System of Units (SI), verification & stamping, manufacture & sale, packaged commodities, consumer protection, offences & penalties, enforcement machinery, and Inter-State uniformity.

What Do the New Rules Provide?

• The rules seek to institutionalise the “One Nation, One Time” framework announced in 2025.
• They require government departments and specified critical sectors to rely on a traceable and authorised Indian Standard Time reference.
• Implementation Period:
  • The rules will become effective 180 days after their publication in the Official Gazette.
  • This transition period is intended to allow institutions to upgrade systems and achieve compliance.
• National Timekeeper:
  • CSIR–National Physical Laboratory (CSIR-NPL) will continue to maintain India’s national reference time.
• IST and UTC:
  • NPL maintains UTC (NPLI), representing India’s realisation of Coordinated Universal Time (UTC).
  • Indian Standard Time is derived as:
    • IST = UTC (NPLI) + 5:30 hours

Why Does Precise Time Synchronisation Matter?

• Contemporary digital infrastructure requires not just an accurate clock but precisely synchronised and traceable timestamps.
• Banking and Digital Payments:
  • Time records help establish when financial transactions were initiated, processed and completed.
• Capital Markets:
  • Accurate timestamps help establish the sequence of orders and trades and can support regulatory and investigative processes.
• Telecommunications:
  • Synchronised clocks enable correlation of server records and help determine when particular network events, such as the use of an IP address, occurred.
• Power Grids:
  • Precise timing assists in coordinating grid operations and reconstructing the sequence of events during system failures.
• Transport:
  • Railways and airports depend upon coordinated scheduling across geographically separated locations.
• Government and Legal Records:
  • A common time reference improves consistency and reliability in official records.
• Cybersecurity:
  • Synchronized system logs help investigators reconstruct the sequence of events during cyberattacks and other security incidents.
• Thus, precise time synchronisation has become an element of digital infrastructure and national security, rather than merely a matter of maintaining accurate clocks.

How Will India Disseminate IST?

• CSIR-NPL will remain the source of India’s national reference time, while dedicated dissemination infrastructure will extend this reference to critical users.
• Time-dissemination laboratories are being established at five Regional Reference Standard Laboratories (RRSLs) in:
  • Ahmedabad;
  • Bengaluru;
  • Bhubaneswar;
  • Faridabad; and
• These facilities are being developed in collaboration with NPL and ISRO.
• A significant development is the White Rabbit Technology-based IST Dissemination Demonstration Network, recently commissioned at Bengaluru.

What is White Rabbit Technology?

• White Rabbit is an open-source technology designed for sub-nanosecond-level clock synchronisation over fibre-optic networks.
• It measures signal-propagation delays and compensates for them, enabling computers located at different geographical locations to remain extremely precisely synchronised.
• Its fibre-based design also reduces dependence on satellite signals at every location.
• This is strategically important because satellite-navigation signals can be vulnerable to:
  • Jamming; and
  • Spoofing.

Role of NavIC and Strategic Significance

• The rules permit the use of Navigation with Indian Constellation (NavIC) and other approved Indian timing sources for IST dissemination.
• This enables a more resilient national timing architecture:

NPL atomic-clock reference → Terrestrial fibre/White Rabbit + NavIC → Synchronised critical infrastructure

• Such an architecture can:
  • Reduce excessive dependence on foreign satellite-navigation systems;
  • Strengthen India’s strategic autonomy;
  • Improve cybersecurity; and
  • Increase the resilience of critical infrastructure.

Issues & Concerns With One Clock

• Solar-Time Mismatch:
  • A single national clock can produce considerable differences between clock time and actual sunrise/sunset patterns across India’s eastern and western regions.
• Regional Inconvenience:
  • A uniform IST may not always correspond conveniently with local school, workplace and economic schedules.
• Productivity Concerns:
  • Availability of daylight differs considerably across regions, which can affect the practical suitability of uniform working hours.
• Centralisation Risk:
  • Greater reliance on one national timing reference makes robust redundancy and backup systems essential.
• Implementation Costs:
  • Upgrading legacy clocks, computer systems and sector-specific infrastructure can impose significant costs.
• Geographical Limitation:
  • A single time zone is less responsive to India’s substantial east–west geographical spread.
• Implementation Challenges:
  • Upgrading legacy clocks and IT infrastructure;
  • Developing interoperable timing standards across sectors;
  • Protecting the national timing network against cyber threats;
  • Maintaining alternative timing sources during network disruptions; and
  • Managing compliance costs, particularly for smaller institutions.

Way Forward

• Successful implementation of the One-Clock framework requires:
  • Sector-specific technical standards;
  • Reliable backup and redundancy mechanisms;
  • Strong cybersecurity safeguards;
  • Interoperability across public and private systems; and
  • Affordable compliance mechanisms for smaller organisations.
• The objective should go beyond simply establishing “one clock” and instead build a secure, resilient, traceable and nationally interoperable timing ecosystem.

2. N-E Models of Waste Management

Context: The Majuli model in Assam and the Tawang model in Arunachal Pradesh demonstrate how community participation, decentralised waste-management systems and locally designed financing mechanisms can improve waste management in rural and geographically challenging areas.

• These models highlight the importance of adapting waste-management systems to local settlement patterns, terrain and community capacity.

About Majuli and Tawang Rural Waste Management Models

Majuli Model

• Central Material Collection Facilities (CMCFs):
  • CMCFs have been established across most panchayats, supplemented by collection facilities at the village level.
• Decentralised Sorting:
  • Non-biodegradable waste is segregated locally before being transported to scrap dealers and recycling facilities.
  • This reduces the quantity of waste requiring final disposal.
• Government–NGO Partnership:
  • Government agencies provide infrastructure and transportation facilities.
  • Organisations such as Saahas contribute through staffing and capacity-building support.

Tawang Model

• Swachchata Divas:
  • Instead of relying entirely on costly door-to-door collection, villagers collectively bring waste to designated locations and participate in its segregation.
  • This approach reduces collection and transportation costs while strengthening community ownership.
• Multi-Category Segregation:
  • Waste is initially divided into 22 categories.
  • At Material Recovery Facilities (MRFs), it is further segregated into approximately 35 categories, enabling better recovery and recycling.
• User Charges:
  • Households contribute approximately ₹50 per month.
  • Shops and cafés pay around ₹100 per month.
  • This creates a locally managed and relatively predictable source of financing for waste-management activities.

Solid Waste Generation in India

• During FY 2021–22, India generated approximately 1,70,000 tonnes of municipal solid waste per day.
  • Around 1,56,000 tonnes was collected.
  • Nearly 54% of the collected waste was treated.
  • Approximately 24% was deposited in landfills.
  • The remaining 22% was unaccounted for, indicating leakages in the waste-management chain.
• According to MoHUA projections, Indian cities could generate approximately 435 million tonnes of solid waste annually by 2050.
• India has only around 645 operational landfills, while the country has approximately 2,452 existing dumpsites.

What are the Difficulties in Managing Waste?

• Changing Patterns of Consumption:
  • Increasing consumption of packaged food, beverages, personal-care products and multi-layered plastics is increasing the volume of non-biodegradable waste, including in rural areas.
• High Collection Costs:
  • Waste collection and transportation become expensive because of:
    • Dispersed settlements;
    • Difficult terrain;
    • Poor road connectivity; and
    • Long distances between collection points and recycling facilities.
  • Open Dumping:
    • In the absence of organised collection systems, waste may be dumped in fields and water bodies or openly burned.
    • This contributes to soil, water and air pollution.
  • Poor Segregation at Source:
    • Wet, dry, sanitary and hazardous waste are frequently mixed at the household level.
    • Such mixing makes recycling, composting and scientific treatment more difficult and expensive.

Government Initiatives

• Solid Waste Management Rules, 2016:
  • Require segregation of waste at source into:
    • Biodegradable waste;
    • Non-biodegradable waste; and
    • Domestic hazardous waste.
  • Promote scientific processing through:
    • Composting;
    • Bio-methanation; and
    • Waste-to-energy technologies.
  • Encourage bulk waste generators such as housing societies and hotels to process their waste locally.
• Swachh Bharat Mission (SBM):
  • SBM-Urban focuses on universal door-to-door waste collection and promotes segregation at source.
  • SBM-Rural supports management of biodegradable waste through measures such as composting and biogas plants in rural areas.
• Waste-to-Energy Projects:
  • The government promotes waste-to-energy facilities to convert suitable non-recyclable waste into electricity, thereby reducing the burden on landfills.
• Extended Producer Responsibility (EPR):
  • EPR places responsibility on producers and manufacturers for managing waste generated after their products are consumed.
  • It is particularly relevant for streams such as plastic waste and e-waste.
• NAMASTE Scheme — National Action for Mechanized Sanitation Ecosystem:
  • Seeks to formally recognise and integrate sanitation workers and waste pickers into the sanitation and waste-management ecosystem.
  • The scheme provides measures including:
    • Occupational safety training;
    • Health protection through Ayushman Bharat-PMJAY; and
    • Capital support for waste collectors.

Way Ahead

• Community Ownership:
  • Citizens should be treated as active stakeholders and co-managers, rather than merely beneficiaries of waste-management services.
• Local Adaptation:
  • Door-to-door collection should be adopted wherever economically and geographically feasible.
  • In scattered settlements and difficult terrain, community-based collection points can offer a more practical alternative.
• User Financing:
  • Affordable, locally determined waste-management charges can provide communities with a sustainable source of revenue.
• Government–Community Partnership:
  • Public agencies can provide infrastructure, technical support and funding, while communities contribute through participation, monitoring and local ownership.
• Market Linkages:
  • Reliable connections with recyclers, scrap dealers and other waste-recovery markets are essential to make segregation economically viable.
• Data Generation:
  • Local authorities should maintain reliable data on:
    • Waste generation;
    • Collection;
    • Segregation;
    • Processing;
    • Disposal; and
    • Operational costs.
  • The Majuli and Tawang models demonstrate that there is no single waste-management solution suitable for every region. Decentralisation, community participation, appropriate technology and sustainable local financing can together create more effective waste-management systems, particularly in rural and geographically difficult areas.
