Setting the Clock

I am trying to figure out how to set this clock. It sets by itself, changes for daylight savings and it remains on after it is unplugged. When you plug it back in the time is still set.

How do I get my smart alarm clock to reset itself automatically since the goverment changed the daylight savings time? Or, if I buy a new one will it have the new time changes?

The Daylight Saving Time settings are not user controlled, so you cannot convert the changeovers to the new schedule - you can only change the time manually. Any new clock or clock radio with automatic settings will work on the new schedule.

Oregon Scientific Model 323a--Atomic clock...the atomic clock keeps setting itself to one hour behind what time it actually is in my time zone...I mannually re-set the clock to the correct time...but when...

Make sure that the clock is set for the correct time zone and that the DST (Daylight Saving Time) function is ON. Also, although not mentioned in the manuals, these clocks will typically jump and hour ahead or behind when the batteries get weak. Replace your batteries if they are more than a year old.

My clock went back one hour on Sunday 10/25, need to get it to move ahead one hour.

The clock program for Daylight savings Time is programmed for the old "third Sunday in October" changeover. The new changeover is the first Sunday in November. The program probably cannot be updated. If there is no button or setting to disable automatic change to Daylight Savings Time you can set the time manually and then change it manually to Daylight Savings on November 1 for the time to be correct.

Daylight Savings Times Changed

We set the time zone to '7' , which is Hawaii time zone where there is no change for daylight savings. This came up because it changed automatically on this morning...and although we can change it back, then it won't change next week when it should. So we're hoping that by setting it to Hawaii it will be a regular clock, we will do the changing...but at least we won't be surprized as we were this AM.

Can't set the time

You can disable the daylight saving time function using the DST switch. Setting the time requires you to slide the 4-position slide switch on the top rear to the right to set the time.
