The git datamodel stores files as a list of names and whether or not they have the executable bit.
If you need to set the ctime/mtime/whatever on the other side you'd do that via some script you'd ship with your repository.
This may not answer your question, but it isn't very clear.

That is not in the tree data structure, see below.

I wish it was an allowable extension, the date could be between the mode and object type.

Yes it's not part of the tree structure, but in this case you can simply set/update the mtime to the date of the last commit that modified the file.
It can be a bit expensive to bootstrap that, and git doesn't help you along at all, you need to do it via hooks or some script you run, but that's a neat way to shove it into the datamodel if you need this for some reason.

Do you see any technical issues with using programmable hooks or something like this would have to be patched in? I am giving it a serious thought to exploring a fix to the Git Daemon over the wire completion issues on Windows. It appears to be a Half Close socket issue.

There are existing scripts which implement this approach, like metastore:
https://github.com/przemoc/metastore
I haven't used it, but I think it's fairly mature, as it has been around since the early days of Git.

I wasn't considering other "metadata" other than time stamps, but I suppose the metadata would include the time stamps, file attributes and possibly "alternate file streams" as well?
Thanks anyway, I will explore it.

Just in case you've missed it, there's an explanation of why Git behaves the way it does in this regard [1].

You can certainly do it with so kind of hook script.
This is how I do thing to maintain the modtimes for a set of patches that I maintain using guilt (git://repo.or.cz/guilt.git). The following is done using Linux, but I imagine you could translate it into something that would work with powershell, or cygwin, or just use the Windows Subsystem for Linux.
#!/bin/sh
stat -c "touch -d @%Y %n" * | sort -k 3 | grep -v "~$" | sort -k3 > timestamps
I have this shell script saved as ~/bin/save-timestamps. The generated file has lines which look this:
touch -d @1496078695 fix-fdatasync-after-extent-manipulation-operations touch -d @1496081597 status
touch -d @1496082752 series
... and when you execute the command, it will restore the timestamps to the value checked into the git repository. If you want to only restore the timestamp of a single file, you can do something like this:
grep timestamps ^fix-fdatasync-after-extent | bash
Cheers,
- Ted
