Time in India: How One Clock Powers Round-the-Clock AI Work

India runs on one time zone. Nicole Junkermann explains why that steady clock gives India a quiet advantage for global teams building and running artificial intelligence.

Anyone you ask in Hyderabad, Delhi or Kochi about the time in India will give you the same answer because India maintains only one time, Indian Standard Time (IST), which is UTC + 5:30. There is no adjustment in this time due to daylight saving time. One such small aspect of the Indian standard time system makes India very comfortable for partnerships around the world.

Nicole Junkermann on India’s single clock

As time in India does not move, the distance between India and other nations will vary depending on whether they change the clock or not. The Europeans and North Americans change their clocks twice a year, whereas the distance between India and the Gulf or Singapore remains unchanged. According to Nicole Junkermann, this is a great present for planning: everyone dealing with Indian teams starts from the same zero point.

Time in India compared with partner cities

A short history of time in India

The tale of the single clock in India is a rather simple one. The Indian Standard Time is defined by the reference meridian of 82.5 degrees east longitude, which passes near Mirzapur in the state of Uttar Pradesh and is approximately in the middle of India. In the absence of a single standard for time, different cities used their own local times, and the great port cities of Mumbai and Kolkata have their clocks too for quite some time now. There are geographical influences too: the sun rises almost two hours earlier in India’s far northeast than it does in the far west.

Why time in India matters for outsourcing and AI

Being located between Europe and the Americas makes India well-suited to work that doesn’t stop. As Nicole Junkermann sees it, the time differences between India and its partner countries make India ideal for a relay model, where one group picks up from the achievements of the other. This is particularly beneficial for artificial intelligence, where machine learning models are trained, tested, and refined all day and night, with the Indians playing their role.

• Follow-the-sun support, with work passing from Europe to India to the Americas
• Monitoring and evaluation of AI systems by teams in India through every hour
• Data review and labelling in India, finished in time for a partner’s morning
• Overnight batch jobs checked by a team in India just starting its day
• Clear handover notes, so nothing is lost between India and its partners

A working day in the India relay

Visualize a regular working day. The early morning hours in India coincide with late morning in Singapore and afternoons in Sydney, which means that the Indian teams will have the time to get any queries from Asia and Australia in the morning itself. The afternoon in India is when Europe wakes up, which makes the afternoon in India the right time to call London or Frankfurt. Late evenings see the beginning of the American working day, which in turn requires a quick handover from India, ensuring that colleagues in New York are ready for their morning calls.

Nicole Junkermann’s habits for teams working with India

Good collaboration across time zones rests on a few easy habits. Teams can record timestamps in UTC and show IST alongside them, agree an overlap window that respects everyone’s working day, and keep a short note at the end of each shift. In her view, AI tools also help with the clock itself, summarising overnight threads, translating handover notes and suggesting meeting times that suit both India and its partners. Plain language helps too: a handover written in India should read just as clearly to a colleague in Europe or the Americas who may be working in a second language.

India, Hyderabad and the wider picture

Cities such as Hyderabad, with its technology districts, research teams and growing community of founders, show how naturally India’s single clock fits global work. From Bengaluru and Chennai to Pune and Kolkata, the same clock links India’s technology cities, which makes coordinating teams across the country wonderfully straightforward. Her reflections in explore that story further, alongside fourteen other Indian cities.

For Nicole Junkermann, the lesson from India is simple. Technology works best when it fits real life and leaves people in charge of the decisions that matter. With one clock, clear habits and thoughtful tools, time in India becomes less a distance to manage and more a working day that India shares with the world.
