WHIZBANG This thing is kind of Buggy. The 'set to now' box works in a different time zone or is not set to recognize AM vs PM. At any rate anything after noon will show as the next day. Suggest manually entering date and time which seems to work fine. I used 24 hr clock times and they show up as regular AM PM in finder.
As for the previous review I found that most File Information is locked by default and must be unlocked using your system password before you can change the creation date. The modification date seems to work fine without unlocking (previous bug not withstanding).
I would not pay for this application in it's current form but for the occasional date change (usually) for sorting reasons in Finder) I can live with the nag.
