Over, over, over, over, over....

From:  "Spenser"

During daylight savings time that would require to set the clock back one hour, if you were to set the clock back 1 hour when the clock hits midnight, then it would be at 11:00 pm yesterday! Then why doesn't that day repeat over and over again forever?

jax responded with this: 

Thats why they make you do it at like 2am or 4am instead of midnight. Just for the braniacs.

Seb helped out here: 

Simply, you don't put the clocks back at midnight. Traditionally, they go back at 2 or 3am depending on where you are from. Then again, some countries don't even bother with daylight savings time at all

brad added this: 

because you don't set your clock back at 12:00am your suppose to set it back at 2:00am to avoid that problem

TB believes this: 

Daylight Saving Time begins for most of the United States at 2 a.m. on the first Sunday of April. Time reverts to standard time at 2 a.m. on the last Sunday of October. In the U.S., each time zone switches at a different time.

don't worry be happy simply answered with this: 

the daylight savings is at 2 AM so don't worry about it. :-)

amrshalakanidr muttered this: 

cause u only do it once a year!!! u don't go back every time it hits 12...u just do that once...the next time it hits 12 that is after an hour...u leave it to progress into 12:01 and so on. simple!

SaxonJF reported this: 

the easy answer is that time does not change at midnight. It always happens between 2AM and 3AM. Even so, with a truly stupid question like that, once could ask, "why doesn't time repeat itself between 2 and 3?" The time passes right by anyway, even if you set your clock back at 4:15 PM to 3:15 PM.

Todd concluded with this: 

In the fall all clocks are set back an hour. But the clocks go from 1:59 am to 1:00 am, instead of going to 2:00 am. Most people change there clocks before going to bed so most clocks don't change like this. But clocks that automatically change (such as the computer clock) change like this. It is very strange to see let me tell you. So changing the clocks back at midnight isn't really true. Even if it were true, the clocks would only be set back once. Changing the clocks back have nothing to do with traveling back in time. Nice idea though.
