Hi- we rebuilt camonitor with EPICS base patched with Andrew Johnson's 
DST fix from last week, to fix this same problem.

Subject: Daylight savings time

Something very weird just happened here and we are still trying to figure 
out why.

Running iocs were updated by just setting the TIMEZONE environment variable 
and all is fine.

Iocs that were rebooted today had the TIMEZONE variable set in a common 
startup script that is called before everything else.  Those IOCS seemed 
to display the correct time but camonitor was reporting the time an hour 
earlier.  The hardware timing module displayed the time an hour later than 
it was. The timing system was not rebooted and had the correct time on the 
hardware link.

We fixed the problem by moving the TIMEZONE setting to the post-startup 
script.

Has anyone else had similar problems?
