Actually, it seems to update once a day alright but the 24 hours are timed 
from the last time it checked for updates.  If you make it check for updates 
manually at 4:44 am, it will check again by itself 24 hours later!   You 
could however, if you heard that something had been updated later in the 
afternoon, force the check and it would reload your update files now showing 
that new file.  Now however, the auto check would now be that afternoon time 
where you forced the check rather than the 4:44 am time.
