Weirdness with system time

[Rick Grubin]

Perhaps someone has seen this before, or recognizes what may be causing
this problem...

I have a Mac II with A/UX on an internal 80MB drive, and an external
20MB drive with MacOS on it.  The external drive is the startup device.

I've just begun to notice that my clock under MacOS has always been one
hour behind.  So I would change it to be correct.  Then, when I ran
A/UX from the Sash partition (internal drive), my UNIX system time is
now one hour ahead.  So I change that time to be correct.  Then when I
go back to MacOS, the clock is one hour behind...  A vicious circle.

Has anyone ever experienced this before?  Does anyone have any ideas
or solutions to this weirdness?  It is really irritating.  Every 
reference of the TZ environment variable is correct (MST7MDT) in the
A/UX init files (at least I believe I've caught every occurence).

I have a startup file called MenuClock101 in my MacOS System Folder,
but its being-there/not-being-there in the System Folder does not seem
to make a difference.

Any help or pointers in the right direction would be greatly appreciated.
Thanks in advance,
