     Cathy,

     As far as I know, 'showtime' shows the software clock setting.  To see
     both current clock settings, you can run the SHOWCLKS.PUBXL.TELESUP
     command.  The HP description of this command and an example follow:

     SHOWCLKS 10/13/89    GREENWICH MEAN TIME (GMT) VALIDATION TOOL

     10/13/89    a support tool to identify (GMT) anomalies

     Description of tool:

     Description    : This program is intended to be a support tool when
                      a problem with Greenwich Mean Time(GMT) is expected.
                      The program makes no attempts to modify any clock
                      variables.  When run, SHOWCLKS will display the values
                      for GMT (retrieved from Processor Dependent Code),
                      the MPE software time(obtained with the CALENDAR and
                      CLOCK intrinsics) and the GMT offset, which is the
                      difference between the two.

                      No user input is required!

    Sample output below:
