MySQL FROM_UNIXTIME() function is used to return the date/datetime from a version of Unix timestamp. The format of return value would be either ‘YYYY-MM-DD HH:MM:SS’ or ‘YYYYMMDDHHMMSS.uuuuuu’ depending upon the context of the function i.e. whether the context is numeric or string.
Following is the syntax for FROM_UNIXTIME −
FROM_UNIXTIME(unix_timestamp, [format])
Here unix_timestamp is the value of Unix timestamp and format includes the format string in which we want to return the value.
Example
mysql> Select FROM_UNIXTIME(1555033470); +---------------------------+ | FROM_UNIXTIME(1555033470) | +---------------------------+ | 2019-04-12 07:14:30 | +---------------------------+ 1 row in set (0.00 sec)
