Subscription Status

A few days ago I removed NIS2011 and did a clean install of 2012 (12-19-12). I clicked on Support>Subscription status and it showed 355 days remaining. I normally get on my PC everyday around 0500 EST. Yesterday when I logged on and ran Live update I noticed that the days remaining still showed 355. sometime during the day the day remaining changed to 354 which was correct. I just cannot pinpoint the time that happened. Samething for yesterday and today when logging on. This morning when I logged on it showed 353 days.
I clicked my subscription status again, connected to the server and it showed 352 days which is correct. I just can't figure out why the days remaining are not subtracting with the start of a new day. When I was running 2011 I didn't  have this problem.
btw, my system clock shows the correct date and time.
