You can do your SETCLOCK TIMEZONE=W5:00. This will start the gradual
accumulation of a 5-hour correction.  Then do a SETCLOCK;CANCEL to stop the
correction.  Next do a SETCLOCK DATE=;TIME= to set the correct time of day.

Subject: SHOWCLOCK and the Time Zone Offset


Fellow MPE/iX folk,

I discovered something odd on my 959/400.  I was preparing for the twice
yearly ritual of changing the TZ offset that occurs this weekend,  I entered
the SHOWCLOCK command and it returned this:

:showclock

SYSTEM TIME: THU, OCT 25, 2001,  2:30:39 PM
CURRENT TIME CORRECTION:            0 SECONDS
TIME ZONE:    0 HOURS  0 MINUTES WESTERN HEMISPHERE

As you can see I have no offset.  An offset of 0 might be fine if I were
somewhere along the Prime Meridian, but living in the Central Time Zone in
the middle of the U. S. A., this seems like a bad thing!  The only thing I
can think of is that when I installed 6.0 pp2 this summer, the clock got
"whacked" some way.  I saw nothing in the Communicator  or the Software
Maintenance Manual about clock "whacking" and don't remember anybody saying
anything about possible gotchas with the system clock and the offset from
GMT.

My question is:  Will I have to go to ISL> and run CLKUTIL, or does anyone
see a more simplified way to fix this issue.  Probably checking the H/W
clock via CLKUTIL is not such a bad idea anyway.  So what I am thinking is
this:

Get the system to ISL> and run CLKUTIL.  Set GMT if it is off

Boot, then run SETCLOCK TIMEZONE=W5:00  That should get me back to where I
should be

Then I can return to CST from DST by issuing the SETCLOCK TIMEZONE=W6:00 on
Sunday Morning.

BTW, the TZ variable is as I think it should be:  CST6CDT.

I can't believe I didn't enter the SHOWCLOCK command even once since the 6.0
update.  It seems that the SHOWTIME command is sufficient most of the time.
Thanks as always for the quality help and input.
