Thanks Tom. I found that picking another setting for timezone did the trick (I'm in Ontario, Canada so we're UTC -5). I had originally picked "ETC/GMT-5" and was having difficulty with 3DM. I switched it to Canada/Eastern and 3DM is working fine now.
I think I have a UPS interface that may not be supported by Open-E. Its an AP9617 management card. It's a card that goes directly in the UPS and to the network (no USB or COM port connections). There is no "master" per se, everything just connects to the IP address of the management card (i.e. when you configure a host to be automatically shutdown by the UPS, you install a shutdown agent, give it the IP address of the UPS, and then on the UPS enter the IP address of the server you've just configured). You can also have the AP9617 send an SNMP trap...
I don’t have anything in my database or tests with this interface for the network. So it could be that we don't have anything for this kind of setup and we have not provided any updates for this interface.
