schedule was stuck in time warp...

@bpizzle noticed that the front page schedule wasn't working correctly,
so I took a look at all recent commits including `front-page.php`.
It turns out that the schedule block was using the time I used during
the 2013 redesign. As in 2012-04-11. Apparently this hasn't been changed
since the redesign last year. @bpizzle says she only noticed the issue
today, and that it couldn't have been broken that long because she uses
the feature frequently.

I have no explanation at this time...
