So just so all you kids here know, Medsua does not presume to know when DST happens for you. She relies on you to tell her.
In the USofA DST happened Sunday morning, March 8 at 2:00am. That means the clocks rolled forward one hour. If you haven't told Medusa to do something about this for YOU, though, then you'll notice posts are time-stamped one hour off of "real" time. You can easily fix this though. Do this:
1) Bonk on User Control Panel. It's up there, on the left, just a little bit below where there's a masthead graphic that says "Forums"
2) Bonk on the Board Preferences tab
3) Toward the bottom find the option labeled Summer Time/DST is in effect and set this to Yes
4) Bonk Save
5) Marvel as all the posts are now correctly time-stamped for you
Cheers.
