What this tool helps you do
Unix timestamps represent an instant relative to the Unix epoch. The same instant can be displayed differently across time zones, and systems may store seconds, milliseconds, microseconds, or nanoseconds.
When it is useful
- Reading API event times
- Converting log timestamps
- Checking expiry claims
- Creating an epoch value from a date
A practical example
A 13-digit contemporary timestamp is commonly milliseconds. Treating it as seconds produces a date far outside the expected range, so confirm precision before interpreting the value.
Limitations and common mistakes
A timestamp alone may not preserve the user's named time zone or daylight-saving rule. Avoid assuming local time, check negative pre-1970 values, and retain precision only as far as the receiving system supports it.
Frequently asked questions
Why are there 10- and 13-digit timestamps?
Ten digits commonly represent seconds and thirteen commonly represent milliseconds.
Does Unix time include a time zone?
It identifies an instant; a time zone is applied when that instant is displayed.
