In the Miscellanous Tool Set, there is a routine called ReadTimeHex ($0D03)
that will return the day-of-the-week, the month, date, year, hour, minute, an
second.  The format is:

          pushword #0                    ; space
          pushword #0                    ;   for
          pushword #0                    ; result
          pushword #0

          _ReadTimeHex

          SHORTACC

          pla
          sta second
          pla
          sta minute
          pla
          sta hour                       ; Hour (0-23)
          pla
          sta curYear                    ; Year - 1900
          pla
          sta day                        ; Date - 1
          pla
          sta month                      ; Month (0-11, 0-Jan)
          pla                            ; unused space
          pla
          sta weekDay                    ; day of week (1-7, 1=Sun)


Hope this helps...
