Re: FSGetCatalogInfo returns mod dates in a deprecated data type: UTCDateTime

If the getter API for UTCDateTime is deprecated I guess we can safely assume the data type is also deprecated.

See:

/*
 *  GetUTCDateTime()   *** DEPRECATED ***

[snip]

The utilities you mention are just bridges for us to use the recommended APIs. I know Larry is always warning us how dangerous and evil assumptions are but I guess my assumption is on the safe side. :)

Apple deprecated all of QuickDraw, including data types that are still in use in other places because newer replacement APIs haven't yet been provided. Likewise for UTCDateTime, there are still a number of non-deprecated routines that use the data type, such as UCConvertUTCDateTimeToCFAbsoluteTime, UCConvertCFAbsoluteTimeToUTCDateTime and File Manager routines that work with the FSCatalogInfo structure.

You could always wrap API calls that directly manipulate UTCDateTime values in standalone routines such that the rest of your code always uses CFAbsoluteTime. Then your wrapper routine can be updated over time to handle both the old way (if still relevant) and new way, once a new way is provided.

It looks like you're assuming that UTCDateTime was deprecated when it was the
functions in UTCUtils.h that were deprecated.  See DateTimeUtils.h for
non-deprecated functions that operate upon UTCDateTime.

Hi Chris, Larry

I knew about converting UTCDateTime to CFAbsoluteTime; that was not
the problem, although I do appreciate the fact that you replied to my
question. What I asked was a way to get rid of UTCDateTime data type
completely by using a more modern API than FSGetCatalogInfo, but I
guess the "deafening silence" concerning my question means there is
none at the moment. :)  Therefore I was planning to use the APIs that
Larry suggested, although it's good to know that you can do that
manually if you wish. :) I could file a bug but I guess Apple is
perfectly aware of that problem when they declared UTCDateTime
deprecated in Tiger. The "deafening silence" is quite understandable. :)
