Unix time ↔ IST and UTC
Developers often need to translate epoch seconds into India Standard Time (UTC+5:30) or UTC. This converter accepts seconds or milliseconds and can turn a datetime (interpreted as IST) back into Unix.
Frequently asked questions
Seconds or milliseconds?
Values with about 13 digits are treated as milliseconds; ~10 digits as seconds.
What is IST?
India Standard Time, Asia/Kolkata, fixed UTC+05:30 (no DST).
Is data uploaded?
No. Conversion uses JavaScript Date and Intl in your browser.
datetime-local timezone?
The picker has no zone; we treat the wall clock as IST (+05:30) when converting to Unix.
