If the DBS Control flag TimeDateWZControl is enabled, the following statements request the current time based on the current session time and time zone.

   SELECT CURRENT_TIME;
   SELECT CURRENT_TIME AT LOCAL;

The result is similar to:

   Current Time(0)
   ---------------
    15:53:34+00:00

When TimeDateWZControl flag is enabled and the session time zone is defined with a time zone string that follows different Daylight Saving Time and standard time zone displacements, then CURRENT_TIME AT LOCAL gives TIME value corresponding to Standard time zone rather than the Daylight Saving Time time zone.

During the Daylight Saving Time period, CURRENT_TIME AT LOCAL follows Standard time zone, whereas CURRENT_TIME follows the Daylight Saving Time zone. During Standard time zone period, both CURRENT_TIME and CURRENT_TIME AT LOCAL follow the standard time zone.
