Continue readingHow UNIX_TIMESTAMP() Works in MariaDB
In MariaDB, UNIX_TIMESTAMP() is a built-in date and time function that returns a Unix timestamp, based on its argument (or lack of argument).
It works like this:
- When called without an argument, it returns a Unix timestamp (seconds since ‘1970-01-01 00:00:00’ UTC) as an unsigned integer.
- When called with an argument, it returns the value of the argument as seconds since ‘1970-01-01 00:00:00’ UTC.
The inverse function of UNIX_TIMESTAMP() is FROM_UNIXTIME().
