Okay, so in 0.18, how would I do so?

This is of more than academic interest for two reasons:
(a) I'm going on a trip soon.  I need to make sure the scheduling data
    is actually correct -now-, before I leave, so I can inspect for
    conflicts and resolve them, etc.
(b) I've just noticed that there's a large gap (several hours) in all
    channels for this coming Wednesday evening, causing all scheduled
    recordings there to fail.  I'd like to refresh this -now-, once
    again because I won't necessarily be able to check it on Tuesday
    to see if the damaged section is restored.  (I assume that Zap2it
    had some sort of DB issue.)

Right, right, I know you're saying this for the record so everyone
doesn't download all days, but there's clearly been some damage to the
scheduling info I got from DD last week, and I need to fix it in the
next 12 hours or so in order to ensure that it -is- fixed.  Please
don't assume I was planning to run this every day---I said at the
beginning that I wasn't.
