AT_TIME_ZONE

The date function used to convert a date or date time value to a given time zone. Takes two arguments, the date to be converted and the timezone. Time zones can be specified either via three-letter code ("UTC", "CST") or via offset ("-6:00"). If the date or datetime value has no specified time zone, this function simply applies the specified timezone to the specified time. If the date or datetime value already has a specified time zone, the specified time will be converted to the value of that time in the time zone parameter.
