Question 1

How accurate is the atomic clock on TimeNumbers?

Accepted Answer

TimeNumbers synchronizes directly with international Stratum-1 atomic clock networks. On any standard broadband or mobile connection, the time you see is accurate within approximately 10 milliseconds (0.01 seconds) of true Coordinated Universal Time (UTC). It is reliable enough for syncing mechanical watches, bidding on time-sensitive auctions, and coordinating international broadcasts.

Question 2

How does TimeNumbers find my exact local time?

Accepted Answer

When you visit TimeNumbers, our system measures the tiny network round-trip time between your browser and our atomic time servers. We instantly detect if your computer or phone clock is drifting fast or slow, and apply a real-time calibration offset so you always see the exact second without installing any software.

Question 3

What is the real difference between UTC and GMT?

Accepted Answer

While GMT (Greenwich Mean Time) and UTC (Coordinated Universal Time) share the exact same current hour and minute, they represent different concepts. GMT is an astronomical time zone tied to the Earth's rotation at the Royal Observatory in Greenwich, London. UTC is the official international scientific standard governed by high-precision atomic clocks. Neither UTC nor GMT ever shifts for Daylight Saving Time.

Question 4

How does the International Meeting Planner find the best overlap time?

Accepted Answer

Our meeting planner takes the work schedules of everyone on your team—usually 9:00 AM to 5:00 PM in their local cities—and aligns them along a 24-hour visual bar. The planner automatically highlights the sweet spot where everyone is awake and working during daylight hours, so you never accidentally schedule a call during a teammate's midnight.

Question 5

When do clocks change for Daylight Saving Time in 2026 and 2027?

Accepted Answer

In the United States and Canada, clocks spring forward 1 hour on the second Sunday in March (March 8, 2026 / March 14, 2027) and fall back on the first Sunday in November (November 1, 2026 / November 7, 2027). In the European Union and the UK, clocks spring forward on the last Sunday in March (March 29, 2026 / March 28, 2027) and fall back on the last Sunday in October (October 25, 2026 / October 31, 2027).
