How are your pogoplugs getting time/date information? Which servers do they contact?
I don't know how to find out via Archlinuxarm. But I can see the log entries on my router from the pogoplug devices for UDP traffic for port 123, and the destination addresses look kind of odd. I was expecting some official sounding servers, but here's what I have:
