I can't seem to get the router to adjust for DST for Mountain Time. Enable Daylight Saving is checked. Time zone is (GMT-07:00) Mountain Time (US/Canada). Daylight Saving Offset is +1:00
Things I've tried that don't work:
1) Unchecking Enable Daylight Saving. Save/reboot. Check Enable Daylight Saving again. Save/reboot. No difference for Mountain Time but makes a difference for Pacific time. See item 5 below.
2) Adjusting the offest to +2:00. Save/reboot. No difference in time so it is completely ignoring this setting.
3) Factory reset. Only settings configured after the reset are the time settings.
4) Tried 3 different NTP servers. Not surprising this has no effect as the time zone and DST information is not part of the protocol.
5) Change time zone to Pacific. Save/reboot. Has correct Pacific time adjusted for DST. Uncheck Enable Daylight Saving. Save/reboot. Correct Pacific time without DST. Change back to Mountain Time and Enable Daylight Saving. Save/reboot. Time is 1 hour behind what it should be for Mountain.
6) Change time zone to Central. Save/reboot. Has correct Central time adjusted for DST. Change back to Mountain Time. Save/reboot. Time is 1 hour behind what it should be for Mountain.
So it seems DST is not working just for Mountain Time. Strange.
FYI. Similar thread I found on version 2.03NA with no resolution.
