8.57 CTIME — Convert a time into a string

Description:

CTIME converts a system time value, such as returned by TIME8, to a string. Unless the application has called setlocale, the output will be in the default locale, of length 24 and of the form ‘Sat Aug 19 18:13:14 1995’. In other locales, a longer string may result.

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 CTIME(TIME, RESULT).

RESULT = CTIME(TIME).

Arguments:

TIME	The type shall be of type INTEGER.
RESULT	The type shall be of type CHARACTER and of default kind. It is an INTENT(OUT) argument. If the length of this variable is too short for the time and date string to fit completely, it will be blank on procedure return.

Return value:

The converted date and time as a string.

Example:

          program test_ctime
              integer(8) :: i
              character(len=30) :: date
              i = time8()
          
              ! Do something, main part of the program
          
              call ctime(i,date)
              print *, 'Program was started on ', date
          end program test_ctime
