PACKTIMEQQ

Portability Subroutine: Packs time and date values.

Module

USE IFPORT

CALL PACKTIMEQQ (timedate,iyr,imon,iday,ihr,imin,isec)

timedate

(Output) INTEGER(4). Packed time and date information.

iyr

(Input) INTEGER(2). Year ( xxxxAD).

imon

(Input) INTEGER(2). Month (1 - 12).

iday

(Input) INTEGER(2). Day (1 - 31)

ihr

(Input) INTEGER(2). Hour (0 - 23)

imin

(Input) INTEGER(2). Minute (0 - 59)

isec

(Input) INTEGER(2). Second (0 - 59)

The input values are interpreted as being in the time zone set on the local computer and following the daylight savings rules for that time zone.

The packed time is the number of seconds since 00:00:00 Greenwich mean time, January 1, 1970. Because packed time values can be numerically compared, you can use PACKTIMEQQ to work with relative date and time values. Use UNPACKTIMEQQ to unpack time information. SETFILETIMEQQ uses packed time.

Example

 USE IFPORT
 INTEGER(2) year, month, day, hour, minute, second,   &
            hund
 INTEGER(4) timedate
 CALL GETDAT (year, month, day)
 CALL GETTIM (hour, minute, second, hund)
 CALL PACKTIMEQQ (timedate, year, month, day, hour,   &
                  minute, second)
 END
