About Unix Timestamps
A Unix timestamp (also known as Epoch time, POSIX time, or Unix Epoch time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC (the Unix Epoch). It is widely used in computing for recording event times, database timestamps, API responses, and log files.
Seconds: Standard Unix timestamp (10 digits, e.g., 1700000000)
Milliseconds: Used by JavaScript, Java, and many APIs (13 digits, e.g., 1700000000000)
Microseconds: Used in high-precision logging and databases (16 digits, e.g., 1700000000000000)
Quick Reference
Unix Epoch: January 1, 1970, 00:00:00 UTC (timestamp = 0)
Y2K: January 1, 2000, 00:00:00 UTC (timestamp = 946684800)
Max 32-bit: January 19, 2038, 03:14:07 UTC (timestamp = 2147483647)
Negative values: Represent dates before January 1, 1970
