What is Unix time?

Unix time counts seconds since 1970-01-01 00:00:00 UTC. Milliseconds are seconds × 1000.

DST and timezone offsets are applied when converting to local time.

FAQ

What is a Unix timestamp?
It’s the number of seconds since 1970-01-01 00:00:00 UTC (ignoring leap seconds). Milliseconds are just the same ×1000.
Does this handle milliseconds?
Yes. Paste either seconds (10 digits) or milliseconds (13 digits); we detect the length.
Why does the local time look different across zones?
Because of time-zone offsets and daylight saving rules; the same instant renders differently in different zones.
