FROM_UNIXTIME()

FROM_UNIXTIME()

Description

The FROM_UNIXTIME() function returns a representation of unix_timestamp as a datetime or character string value. The value returned is expressed using the session time zone. For example, the return value is in ‘YYYYY-MM-DD HH:MM:SS’ format or YYYYMMDDHHMMSS. unix_timestamp is an internal timestamp value representing seconds since 1970-01-01 00:00:00 UTC, such as produced by the UNIX_TIMESTAMP() function.

Syntax

> FROM_UNIXTIME(unix_timestamp[,format])

Arguments

Arguments Description

format Optional. A format string indicating the format of the return value.
If the format is omitted, this function returns a DATETIME value.
If the format is NULL, this function returns NULL.
If the format is supplied, the value returned is a VARCHAR.

unix_timestamp Required.
If the unix_timestamp is NULL, this function returns NULL.
If the unix_timestamp is an integer, the fractional seconds precision of the DATETIME is zero. When unix_timestamp is a decimal value, the fractional seconds precision of the DATETIME is the same as the precision of the decimal value, up to a maximum of 6. When unix_timestamp is a floating point number, the fractional seconds precision of the datetime is 6.

Arguments	Description
format	Optional. A format string indicating the format of the return value. If the format is omitted, this function returns a DATETIME value. If the format is `NULL`, this function returns `NULL`. If the format is supplied, the value returned is a VARCHAR.
unix_timestamp	Required. If the unix_timestamp is `NULL`, this function returns `NULL`. If the unix_timestamp is an integer, the fractional seconds precision of the `DATETIME` is zero. When `unix_timestamp` is a decimal value, the fractional seconds precision of the `DATETIME` is the same as the precision of the decimal value, up to a maximum of 6. When unix_timestamp is a floating point number, the fractional seconds precision of the datetime is 6.
