MST or EST??

Okay so last night was a bust.  Midnight hit, and we were still on and on with Clint about all the crazy stuff that has been going down her lately.  Are we playing by mountain standard time or eastern standard time, cause if it is MST, we were in be before midnight.  (tee hee hee)  Hopefully we will do better today.  I have been awake for 40 minuites and haven't switched it yet :)  (Although Jacob is at the hospital rounding, and the kids are watching a movie, so not having any one to talk to does make it a little easier :)
