TZ_OFFSET


Syntax

tz_offset::=
Description of tz_offset.gif follows
Description of the illustration tz_offset.gif


Purpose

TZ_OFFSET returns the time zone offset corresponding to the argument based on the date the statement is executed. You can enter a valid time zone name, a time zone offset from UTC (which simply returns itself), or the keyword SESSIONTIMEZONE or DBTIMEZONE. For a listing of valid values for time_zone_name, query the TZNAME column of the V$TIMEZONE_NAMES dynamic performance view.


Note:

Timezone region names are needed by the daylight savings feature. The region names are stored in two time zone files. The default time zone file is a small file containing only the most common time zones to maximize performance. If your time zone is not in the default file, then you will not have daylight savings support until you provide a path to the complete (larger) file by way of the ORA_TZFILE environment variable.
