I'm seeing the same issue and I'm running 12-hour format. I switched from ISY (where it ran perfectly) to EISY two days ago, and now some of my From/To using Sunset/Sunrise (next day) programs appear to not be running correctly. The port went great, I have a new PLM (replaced a bad one a couple weeks ago) and all my scenes, etc look to be correct. I'm betting (hoping) there's a bug somewhere with this on the EISY. I need to go back and pay more attention while running some tests, but I swear that during the "Then" time of day, if I run the program Run If - the Then doesn't trip. It Does appear that the Else portion Is running when the time period expires - its just the Then portion that doesn't seem to trip correctly. I have several programs running for different locations - front porch light, coach lights, low-voltage landscaping lights, and they All don't turn ON (then portion) but when I turn them on by hand, they do turn OFF correctly (else portion.) I HOPE what I said here makes sense!
