FDATE — Get the current time as a string ¶FDATE(DATE) returns the current date (using the same format as
CTIME — Convert a time into a string) in DATE. It is equivalent to CALL CTIME(DATE,
TIME()).
This intrinsic is provided in both subroutine and function forms; however, only one form can be used in any given program unit.
