Vince,

?

I live in Arizona too.? I do not see any problems with the ¡®local time¡¯ that OccultWatcher produces.? I keep two columns up in OccultWatcher, one for UT and one for Local Time.? Both before and after the dates that you report are the transition to DST, OccultWatcher shows a 7-hour differential between UT and Local Time.? I can not find a problem.? Also, I could not find a place in OccultWatcher to set the time zone of DST.? Even the site files don¡¯t seem to allow for those settings.

[Edited Message Follows]

I'm in Arizona, USA which doesn't follow DST.

I was looking at the Europa/Io event on March 5th and the software provides a local time for the event of 6:29am.
I loaded up Stellarium to see the big picture and the event doesn't appear to take place till 7:29am local time.In Stellarium I have my time zone set to Phoenix (mountain time) and have disabled DST, and since I haven't noticed any issues before, I believe Stellarium is configured correctly.

Is there a setting in Occult Watcher I might have missed regarding DST?

Oh, a couple more pieces of evidence.
I have a couple of additional planet satellite events, one on 17Mar and the other on 29Mar. These two events agree with what Stellarium shows.

DST doesn't kick in until the morning of 7Mar, so the first event on the 5th is before DST while the other two events are after DST is "on".
