The time you see comes from your own device

ExactTime does not operate an atomic clock and does not synchronise your computer. It reads the current instant from your device's system clock and converts it into local time for each city using the IANA time zone database supplied with your browser and operating system. If your device clock is fast, slow, or set to the wrong zone, every reading on this site inherits that error.

Keeping automatic network time synchronisation enabled on your device is the single best way to make the display trustworthy. Our FAQ explains what to check when two devices disagree.

Provided "as is"

All information on this site — clock readings, offsets, week numbers, sunrise and sunset calculations, and the editorial guides — is provided for general information only, on an "as is" basis, without warranty of absolute accuracy, completeness, or availability. Sunrise and sunset figures are astronomical approximations that ignore local terrain, elevation and atmospheric conditions and may differ from observed values by minutes.

Not for critical timing

Do not rely on ExactTime where an error could cause harm, loss or legal consequence. In particular, it must not be used as a time reference for:

• legal or regulatory purposes, including filing deadlines, contractual time limits, notarisation, evidence timestamps or court schedules;
• medical purposes, including medication timing, clinical procedures or emergency response;
• aviation, maritime, rail or other transport operations, navigation or dispatch;
• financial activity, including trading, settlement, auction closes, expiries or any market cut-off;
• scientific measurement, industrial control, broadcasting or security systems requiring traceable time.

For those uses, consult an authoritative source such as your national metrology institute or a certified, traceable time service, and follow the timing requirements of the relevant operator or regulator.

Not professional advice

The guides are general educational content, not legal, financial, medical or professional advice. Time zone and daylight saving rules are set by governments and can change with little notice; verify anything consequential against an official announcement.
