Need to extract the File modification date of the files that I am
opening in my application.
For the same, I use the following code snippet:
FSCatalogInfo catInfo;
OSErr err = FSGetCatalogInfo (&fsRef, kFSCatInfoContentMod,
&catInfo, NULL, NULL, NULL);
if (noErr == err)
{
UTCDateTime dateTime = catInfo.contentModDate;
LocalDateTime ldt;
ConvertUTCToLocalDateTime(&dateTime, &ldt);
}
The date/time (in ldt) which I get here has a huge difference (in
months), with what I see when I do Get Info of the file in the
Finder.
As it stands, I can't see anything wrong with the above code.
However, you're really only showing half the story here.
Specifically, you don't show how you convert ldt to a string (or
whatever date representation you're using). The error might be there.
My suggestion: run FSMegaInfo against the file and see what it
displays. It should agree with the Finder's result. If it does,
then you have a bug in your code and you can compare it to the
FSMegaInfo source to see what's going wrong. OTOH, if FSMegaInfo
also shows the wrong results, well, I'm confused (-:

The folowing is an example of how to use FSMegaInfo to get this value:
$ FSMegaInfo FSGetCatalogInfo -kFSCatInfoContentMod /mach_kernel
name = 'mach_kernel'
catalogInfo:
contentModDate = 0.3321410102.0 (Tuesday, 31 March 2009 22:55:02 PDT)
