Teradata Vantage™
Teradata requests that customers open an incident so that Teradata Support can assist you in changing time zone settings on your system.

If you do not need Daylight Saving Time, you can set the time using the DBS Control utility settings SystemTimeZoneHour and SystemTimeZoneMinute.

To redefine your time zone, check the list of available time zone strings and their rules in /usr/tdbms/etc/tdlocaledef_tzrules.txt. These rules are also in the GetTimeZoneDisplacement UDF. To change a time zone string and rules, you must change both the GetTimeZoneDisplacement UDF and tdlocaledef.

For more information, see “Adding or Modifying Time Zone Strings” under the topic “GetTimeZoneDisplacement” in Teradata Vantage™ - SQL Date and Time Functions and Expressions, B035-1211 and DBS Control utility and Teradata Locale Definition utility in Teradata Vantage™ - Database Utilities, B035-1102.
