This example shows the effect of the DBS Control flag TimeDateWZControl on the results returned by CURRENT_TIMESTAMP when the function is specified without an AT clause or with an AT LOCAL clause.
Assume the following:
- The time local to Vantage is 11:59:00 Coordinated Universal Time (UTC), January 31, 2010.
- User TK lives in Tokyo, and has a time zone defined as +9 hours offset from UTC.
- User LA lives in Los Angeles, and has a time zone defined as -8 hours offset from UTC.
- User TK and User LA run the CURRENT_TIMESTAMP function at exactly the same time.
If the TimeDateWZControl flag is enabled:
For User TK, the CURRENT_TIMESTAMP function returns:
2010-02-01 10:59:00.000000+09:00
For User LA, the CURRENT_TIMESTAMP function returns:
2010-01-31 16:59:00.000000-08:00
If the TimeDateWZControl flag is disabled:
For User TK, the CURRENT_TIMESTAMP function returns:
2010-01-31 11:59:00.000000+09:00
For User LA, the CURRENT_TIMESTAMP function returns:
2010-01-31 11:59:00.000000-08:00
