Frequently asked questions
What is an epoch (Unix) timestamp?
It is the number of seconds since 1 January 1970 00:00:00 UTC. Many systems also use milliseconds, microseconds or nanoseconds.
How does it know if my number is seconds or milliseconds?
It looks at the number of digits: up to 11 digits is treated as seconds, 12 to 14 as milliseconds, 15 to 17 as microseconds and longer as nanoseconds.
How do I convert IST to UTC?
Pick your date and time, choose IST (India) as the zone, and UTC appears in the results. IST is UTC+5:30 all year with no daylight saving.
Does it handle daylight saving time?
Yes. Conversions use your browser's time zone database, so US and European daylight saving changes are applied for the date you choose.
Is my data sent anywhere?
No. Everything is calculated in your browser.
