Have a problem that just started in a 14 year old home. The masterbedroom outlets have suddenly become unfriendly to our LED alarm. When plugged into any of these outlets , "time flys". When moved to other household outlets, there is no problem. I am seeing 110 volts at these outlets and any where around 110 to 113 at other outlets. Any ideas on what to look for? there are 4 different outlets in this room that do the same to the clock.
