CONVERT_TZ

Syntax

CONVERT_TZ (dateobj, oldtz, newtz)

Arguments

date_obj: A valid DATE, DATETIME, or parseable date string.
old_tz and new_tz: Any valid timezone identifier.

Important

Timezone identifiers may be explicit intervals or named zones. Explicit intervals are in the form +10:00 or -3:30 and are counted from UTC. Named timezones are in the form America/Mazatlan or EST.

The list of supported timezone names is derived from https://www.iana.org/time-zones.

A copy of the timezones list is included in a text file -- memsql_timezones.txt -- in the share directory of your SingleStore installation directory. The timezone names are not derived from any settings on the host operating system.

Return Type

A DATE or DATETIME object. If date_obj, old_tz, or new_tz is not valid, returns NULL.
