Hey all. This is just a suggestion for the Redump database.
Currently we report EXE dates for PS1/PS2 games based off of the file time stamps on the default executable the game is loading. While other systems (especially ones that don't conform to traditional disc based file systems) may not always report the same information, I did notice that Microsoft Xbox games do contain this information in every default.xbe as part of the standard certificate information.

For example, in "Tim Burton's The Nightmare Before Christmas: Oogie's Revenge" (NTSC/US), at 0x114 in the .xbe - the dwTimeDate information is stored in four bytes little endian. In this case, my copy is 42E44C54 big endian, or Jul 24 21:20:04 2005.
Regardless, I think this information is useful for differentiating between different versions of games. This information is especially crucial for us, since we work with prototypes of games a lot and the information from the comparable retail version isn't readily available.
If you're interested in seeing this information for yourself, I would recommend XBE Explorer which you can grab at the bottom:

It'd be nice if this information could be gathered with a script on an entire set and just imported into Redump.org's database. Maybe eventually DICUI could also have the means of getting this information as well to make submissions easier too...
