+
+ Description: Returns data on the real-time clock and date in a form
+ compatible with the representations defined in ISO 8601:1988.
+
+ Class: Non-elemental subroutine.
+
+ Arguments:
+
+ DATE (optional) shall be scalar and of type default character, and
+ shall be of length at least 8 in order to contain the complete
+ value. It is an INTENT (OUT) argument. Its leftmost 8 characters
+ are assigned a value of the form CCYYMMDD, where CC is the century,
+ YY the year within the century, MM the month within the year, and
+ DD the day within the month. If there is no date available, they
+ are assigned blanks.
+
+ TIME (optional) shall be scalar and of type default character, and
+ shall be of length at least 10 in order to contain the complete
+ value. It is an INTENT (OUT) argument. Its leftmost 10 characters
+ are assigned a value of the form hhmmss.sss, where hh is the hour
+ of the day, mm is the minutes of the hour, and ss.sss is the
+ seconds and milliseconds of the minute. If there is no clock
+ available, they are assigned blanks.
+
+ ZONE (optional) shall be scalar and of type default character, and
+ shall be of length at least 5 in order to contain the complete
+ value. It is an INTENT (OUT) argument. Its leftmost 5 characters
+ are assigned a value of the form ±hhmm, where hh and mm are the
+ time difference with respect to Coordinated Universal Time (UTC) in
+ hours and parts of an hour expressed in minutes, respectively. If
+ there is no clock available, they are assigned blanks.
+
+ VALUES (optional) shall be of type default integer and of rank
+ one. It is an INTENT (OUT) argument. Its size shall be at least
+ 8. The values returned in VALUES are as follows:
+
+ VALUES (1) the year (for example, 2003), or HUGE (0) if there is
+ no date available;
+
+ VALUES (2) the month of the year, or HUGE (0) if there
+ is no date available;
+
+ VALUES (3) the day of the month, or HUGE (0) if there is no date
+ available;
+
+ VALUES (4) the time difference with respect to Coordinated
+ Universal Time (UTC) in minutes, or HUGE (0) if this information
+ is not available;
+
+ VALUES (5) the hour of the day, in the range of 0 to 23, or HUGE
+ (0) if there is no clock;
+
+ VALUES (6) the minutes of the hour, in the range 0 to 59, or
+ HUGE (0) if there is no clock;
+
+ VALUES (7) the seconds of the minute, in the range 0 to 60, or
+ HUGE (0) if there is no clock;
+
+ VALUES (8) the milliseconds of the second, in the range 0 to
+ 999, or HUGE (0) if there is no clock.
+
+ NULL pointer represent missing OPTIONAL arguments. All arguments
+ have INTENT(OUT). Because of the -i8 option, we must implement
+ VALUES for INTEGER(kind=4) and INTEGER(kind=8).
+
+ Based on libU77's date_time_.c.
+
+ TODO :
+ - Check year boundaries.
+ - There is no STDC/POSIX way to get VALUES(8). A GNUish way may
+ be to use ftime.
