I have the TMZ set for Eastern. When I click on the Done button under the NTP section, the time comes up 1 hour off. It also is off after a power up. If I click on the Sync button it displays the correct time. Click on the Done button again (sometimes have to click on it twice) and we are back to 1 hour off. If I set the TMZ for GMT then I end up with a 4 hour difference. The Synced time is not correct for England it is still Eastern time. The time after clicking Done button may be correct, as it is 4 hours later. It almost seems that the Time Zone is set in two different places and one of them is stuck on Eastern.
Is there a correction for this problem? Is there a way to force a Time Sync?
