Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC (the Unix epoch). It is widely used in programming to represent dates and times.
What is the difference between Unix timestamp in seconds and milliseconds?
A Unix timestamp in seconds is typically 10 digits, while milliseconds is 13 digits. JavaScript uses milliseconds (Date.now()), while most Unix systems use seconds.
Will Unix timestamps run out?
The 32-bit Unix timestamp will overflow on January 19, 2038 (the "Year 2038 problem"). Most modern systems use 64-bit timestamps, which will last billions of years.
How do I get the current Unix timestamp in code?
In JavaScript use Math.floor(Date.now() / 1000), in Python use int(time.time()), and in PHP use time(). All return the current time as seconds since the Unix epoch.
