Notice The Rover Tracks On The Mars Surface.
Patience my friend. Mars loses 40 minutes each day. Every 18 days it's going to slowly slip back 12 hours in relation to time here.
Also, on the 24th of this month the Opportunity lander will plop down on THE OTHER SIDE of Mars. That should be 8-12 hours off from the Spirit site. So you can see that before long we will be having daytime Martian activity, in fact it will probably be going 24 hours as the two Mars sites alternate between day and night. SO it won't matter which time zone you are in.
