In a slightly different form:

date --date="Mar 10 15:00:00 UTC 2007"
Sat Mar 10 09:00:00 CST 2007

date --date="Mar 11 15:00:00 UTC 2007"
Sun Mar 11 10:00:00 CDT 2007

You see in the output of these date commands that the timezone is listed as CST on March 10 and CDT on March 11, which is correct. You can run the same to commands to determine whether your system also returns the correct timezones on those dates. (Given that I'm running stable and get correct results, I expect that you'll be fine as long as you're up-to-date with whichever branch you're running.)
