I had my 310XT do the March 2007 deal a couple of times for indoor workouts, too. Not every time. Just a couple. I was able to "fix" the files. But, it was a pain in the @$$. So, I did some digging on the Garmin forums.
The solution I found was, instead of turning on the unit before an indoor workout and immediately disabling the GPS, let it lock onto satellites first. Then, disable the GPS.
When it locks onto satellites, it updates the time/date. And, as long as you don't turn the unit off again before disabling GPS and doing your workout, it should keep the correct time/date.
If my unit asks me if I'm indoors when I turn it on, I select no and let it lock onto satellites before manually disabling GPS.
I never had this issue with my 305. And, we shouldn't have it with the 310XT. But... It's a minor inconvenience for an otherwise excellent tool. So, I'll live with it.
