TO_TIMESTAMP Function

The TO_TIMESTAMP function interprets a character string based on the time format given as an argument, converts it to a TIMESTAMP type value, and returns it. For the format, see TO_CHAR Function (date_time). If a format is not specified, the "HH:MI[:SS] [am|pm] MM/DD/YYYY" format is applied by default.
