Its not a critical issue for most cases where Escalation run times are often arbitrarily selected at the least active times. But if a slight miss does get noticed, it could mean that something that was fairly important, may have not been triggered at that expected time which could possibly be David’s case..
Most of us (including me) never even noticed that until David pointed it out.. We may have possibly gone through the rest of our merry ARS lives not worrying about it..

The way escalations work is to calculate when things should NEXT fire and that is what is keyed off of. The calculation is not considering that DST change may be crossed for the next fire time (a fair question is why not and that is something that could be submitted as a bug, but the escalation does run and for one time, it is 1 hour off so is it a critical issue? but, definitely feel free to submit the bug). You should find all back on track after the first firing. Now, the comment about restarting the server. Why does that "fix" things? Well, when you restart the server, we have to calculate all the next fire times so the restart after the change in DST will calculate the fire times correctly even for the first firing interval. It isn't that a restart is required, it is just that the restart causes a recalculation of the firing times. NOTE however that any interval fired operation would not have any issue with the one hour off and a restart of the system will reset the interval counter so the current interval will get longer for the interval based escalations – however long it has been since the last run plus the interval for the first interval. I just wanted to explain what effect the restart had on the issue and why it seemed to "fix" a problem. Again, the answer was already there, I just wanted to confirm it and offer a bit more information about the affect on interval escalations.

(You can tell by watching the Escalation Log and seeing that each escalation states) (enabled) : going to fire in xxxx seconds It would only be able to do that if it is calculated at the time of the last run (to know how many seconds until the next run).

But if what you said applies anyway, I should find out tomorrow when it’s supposed to run again.

I believe all escalation next run times are computed when they run (and are in seconds until next run) so if “A” had not run since the time change it would have been calculated to run x seconds from the last time (and with the time change that would be 1 hour later than you thought) Fred From: Action Request System discussion list(ARSList) [mailto:arslist@ARSLIST.ORG] On Behalf Of David Durling Sent: Monday, March 12, 2012 12:56 PM To: arslist@ARSLIST.ORG Subject: Re: Where does $DATE$ come from? ** Dave, So you’ve had to restart arsystem server to get things back in sync? I had an issue this morning where one escalation (“A”) scheduled for 8:00 went off at 9:00, yet another escalation (“B”) scheduled for 8:05 went off at the correct time. Differences I could think of: escalation A came from workflow originally built on a 6.0 server (and it’s set to run on specific weekdays) , and B was built on our current 7.5 server (and it’s set to run every day).

We have seen some issues with things being off an hour after a time change until we cycle services. That's mostly dealing with escalations.

Is it an Active Link? Or a Filter/Escalation? In case of an Active Link, the $DATE$ would taken from the client. In case of server side workflow objects, Filters or Escalations, they are set from the AR System application server (not the database application server).

This may seem like a strange question but yesterday I had a case where $TIMESTAMP$ was work correctly and diary field entries were correct but the $DATE$ was on hour behind as 3/10/2012 23:00:00 PM.
