Re: Windows Item Date

I think video typically uses XMP not EXIF.  If there isn't an existing reader for it you'd need to write one or find a library.

If it was me I'd use ExifTool because it supports everything and you don't have to maintain it.  You can get it to format its output in an easy-to-parse way (for timestamps this includes seconds since the Unix epoch, including fractional seconds if you want that).
