This statement is a Teradata extension to the ANSI SQL:2011 standard.

The AT clause is ANSI SQL:2011 compliant.

As an extension to ANSI, the AT clause is supported when using Teradata Conversion Syntax to convert from TIME (with or without time zone) to TIME WITH TIME ZONE. In addition, you can specify the time zone displacement using additional expressions besides an INTERVAL expression.

TIME (without time zone) is not ANSI SQL:2011 compliant. Teradata Database internally converts a TIME value to UTC based on the current session time zone or on a specified time zone.
