Unix timestamp FAQ
What is a Unix timestamp?
It is the number of seconds that have passed since 00:00:00 UTC on 1 January 1970, called the Unix epoch. Because it is a plain count with no time zone, it is the usual way computers store an instant.
Is my number in seconds or milliseconds?
Seconds timestamps for today are 10 digits; milliseconds are 13. This converter treats anything above 100,000,000,000 as milliseconds, which is correct for every date after 1973.
What is the year 2038 problem?
A signed 32-bit timestamp overflows at 03:14:07 UTC on 19 January 2038. Systems that still store time in 32 bits would wrap to 1901. Modern systems use 64-bit timestamps, which last for about 292 billion years.
