How come once in a while my clock goes back a hour?

[hi!]

I found this very strange? I know we had a spring back but I changed the clock back
but once in a while My clock goes back an hour???? (of course I change it back) Is that what is missing up my internet connection? why is this happening? thank you

It seems that you change your clock back every time Windows adjust for DST. What Windows does is that every now and then Windows contacts Microsoft's server's and synchs it with their server time. This will undo you manual changes. To stop the clock syncing, go to the clock's settings and click the "Internet Time" tab. Then there should be a button labeled "Change settings". click on it. Then on the pop-up window, uncheck "Synchronize"
