Syntax
CONVERT_TZ(dt,from_tz,to_tz)
Purpose
CONVERT_TZ() converts the datetime value specified by dt from the time zone specified by from_tz to the time zone specified by to_tz and returns the result. It returns NULL if the dt argument is invalid.
If the value obtained by converting the datetime value from the time zone specified by from_tz to the UTC time exceeds the value range of TIMESTAMP, the conversion is aborted. For more information about the value range of the TIMESTAMP type, see DATE, DATETIME, and TIMESTAMP types.
