You can do it 2 ways.
At system level
You might need to change the setting for the DBS Control flag TimeDateWZControl.
At Session Level
SET TIME ZONE 'GMT+5:30' ( This is India Time zone where they don't use Daylight savings and the time '2009-03-08 02:01:05' is a valid time there)
run the update SQL, you should see the data as you expected.
If you want to check the allowed time zone strings please refer to below link.
I am not able to system level Setting (set TimeDateWZControl)
Not sure what you mean by "enable" UTC. You can certainly play with TimeDateWZControl setting on a TD Express VM; but please contact Teradata support for assistance before changing this value on a live system.
