FAQ

What is a Unix timestamp?

A Unix timestamp is the number of seconds elapsed since 1970-01-01 00:00:00 UTC, not counting leap seconds.

Why do some timestamps have 13 digits?

13-digit timestamps are usually Unix milliseconds. Divide by 1000 to get Unix seconds.

Does timezone change the timestamp?

No. A Unix timestamp represents one absolute instant. Timezone changes only how that instant is displayed.
