Converting mod date from FSCatalogInfo to NSDate

Hi

I'm storing some file information in a database and need to convert 
the file modification date returned from FSCatalogInfo to either an 
NSDate or an NSCalendarDate. I found a link here:  http://
www.cocoabuilder.com/archive/message/cocoa/2001/8/1/45890 but all he 
solutions listed in that thread seem to use deprecated functions and/
or methods. Is there a newer way to convert a file modification date 
to an NSDate?

I need to use FSCatalogInfo instead of [NSFileManager 
attributesAtPath:...] to get some info NSFileManager doesn't return 
(like the directory valence)

Thanks

Ken
