I have a PMC2 in the field controlling outdoor lighting for a customer. I got an email saying the the schedule didn't adjust for the recent time change. The processor has updated firmware and the " Adjust clock for daylight savings time" is enabled. The processor time was correct the last time I was there.
Has anyone run into this? Is there something else I have missed?

Not sure how (or if) the processor is getting clock updates from an external source, but perhaps the GMTOFFSET isn't set correctly, relative to the location of the processor?
Does the program in question have a CLOCK symbol with the appropriate parameter setting?
Is the console command OLDUSDST set to 'off'?

One additional bit of clarification...the GMTOFFSET value is referenced in minutes, not hours. The US Eastern Timezone would be -300 (-5 * 60).

In the system properties in SB, they allow you to select your location by long and lat, and allow for dst clock adjustment enablement and that's about it....will have to see what's going on in the back end when I hook up to the processor.....

Also check the firmware version, they changed how DST offset works on clock drivers in the latest.
also an FYI the new 3 series(like the PMC3) has built in functionality to sync with a time server.

Definitely check the firmware. Also, if you have scheduler enabled and the client uses it make sure they didn't change the scheduler settings for the lights that are being controlled. It has happened to me before where they go in and play around, edit the schedule, and things don't come on the way they should. I never give them the option with scheduler unless they ask about it.

Firmware is v4.003.0015 which is the latest and I don't enable the scheduler for the very reason you mentioned
