My Clock Display Keeps Changing!

Every now and then, my time clock display at the bottom right hand of my screen becomes incorrect.

I.E...It'll say 12:51, when it's really 1:51. I know how to change it back, but WHY is it doing this??

 

Agree with Halo. It depends on where you live and whether your country/state has daylight saving. Here, in Australia, the Eastern States, plus ACT, have daylight saving in Summer, but Queensland (where i live) does not. All of them are on GMT +10 hours, but if I was to set up my time zone as Sydney (instead of Brisbane), my times would also be an hour out in Summer if I ticked adjust for daylight saving. In Winter, times are OK, but in Summer an hour out. Bazza.

Check to make sure that your Time Zone is correct for where you live. Pacific is the default that Windows is set for, and when DST is set, it can cause it to change when you change it for where you live (ie Eastern, not Pacific).
