How Unix Timestamps Work

A Unix timestamp counts the number of seconds since the Unix Epoch — January 1, 1970 00:00:00 UTC. It provides a universal, timezone-independent way to represent time.

Key Facts

Frequently Asked Questions

What is a Unix timestamp?
A Unix timestamp is the number of seconds since January 1, 1970 00:00:00 UTC. It is used in programming and databases to represent dates.
What is the Year 2038 problem?
32-bit systems store timestamps as signed 32-bit integers, maxing at Jan 19, 2038. After that, overflow occurs. 64-bit systems are not affected.
Are timestamps affected by timezones?
No, Unix timestamps are always UTC. Apply timezone offset when converting to human-readable dates.
Seconds vs milliseconds?
Seconds timestamps have 10 digits. Milliseconds (used by JavaScript) have 13 digits. This tool auto-detects both.

What is a Unix timestamp?

A Unix timestamp is the number of seconds elapsed since 00:00:00 UTC on 1 January 1970, and a converter translates it to and from a human-readable date in any time zone.

SnoopTool converts in both directions, shows the current epoch live, and renders the result in UTC, IST and your local zone at once. Millisecond timestamps (13 digits) are detected automatically.
