From what I know about this, it is easier for you to change the time in your profile. This clock is set to Greenwich time and I guess it doesn't change back. If this is true, go to your profile and change the time to -5 for Eastern, -6 for Central, -7 for Mountain and -8 for Pacific. I hope this helps.
For Eastern time you put in a minus sign and a five -5
You do this in your profile down towards the bottom in that little box. It says it is set for eastern, but it is set for Greenwich time, so you need to do this to make it correct for you.
