NAME
        datestamp -- obtain the date and time in internal format

    SYNOPSIS
        ds = DateStamp( ds );
        D0              D1

        struct datestamp *datestamp(struct datestamp *)

    FUNCTION
        DateStamp() takes a structure of three longwords that is set to the
        current time.  The first element in the vector is a count of the
        number of days.  The second element is the number of minutes elapsed
        in the day.  The third is the number of ticks elapsed in the current
        minute.  A tick happens 50 times a second.  DateStamp() ensures that
        the day and minute are consistent.  All three elements are zero if
        the date is unset. DateStamp() currently only returns even
        multiples of 50 ticks.  Therefore the time you get is always an even
        number of ticks.

        Time is measured from Jan 1, 1978.

    INPUTS
        ds - pointer a struct datestamp

    RESULTS
        The array is filled as described and returned (for pre-V36
        compabability).
