About Unix Timestamp

Definition

Unix Timestamp (Unix Epoch) is the number of seconds that have elapsed since 1970-01-01 00:00:00 UTC, not including leap seconds. It is a standard way to represent time in computing systems.

Common Programming Examples

JavaScript: Date.now() → millisecond timestamp; new Date(ts*1000) → Date
Python: time.time() → seconds; datetime.fromtimestamp(ts)
Shell: date +%s → seconds; date -d @1700000000
