Just found out yesterday. The clock in my S1 unit is showing one hour behind. I am in Ontario Canada GMT -5.00 time zone. I tried to reset the region setting but no luck. Switched the daylight saving time feature from "auto" to "never" and powered off/on. The time is still one hour behind. No manual clock setting button can be found in this unit. Looks like we have to wait until Pioneer release next patch set to include the new DST rules.
