9.105 FDATE — Get the current time as a string

Description:

FDATE(DATE) returns the current date (using the same format as CTIME) 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.

Standard:

GNU extension

Class:

Subroutine, function

Syntax:
CALL FDATE(DATE).
DATE = FDATE().
Arguments:
DATE The type shall be of type CHARACTER of the default kind. It is an INTENT(OUT) argument. If the length of this variable is too short for the date and time string to fit completely, it will be blank on procedure return.
Return value:

The current date and time as a string.

Example:
program test_fdate
    integer(8) :: i, j
    character(len=30) :: date
    call fdate(date)
    print *, 'Program started on ', date
    do i = 1, 100000000 ! Just a delay
        j = i * i - i
    end do
    call fdate(date)
    print *, 'Program ended on ', date
end program test_fdate
