/* DATE_AND_TIME ([DATE, TIME, ZONE, VALUES])
Description: Returns data on the real-time clock and date in a form
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.
+ DATE (optional) shall be scalar and of type default character.
+ It is an INTENT(OUT) argument. It is 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.
+ It is an INTENT(OUT) argument. It is 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.
+ It is an INTENT(OUT) argument. It is 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
char zone[ZONE_LEN + 1];
