This is one way I deal with the fact that git has no option to respect mtime.

powershell use-commit-times.ps1

'git whatchanged' is nominated for removal.
If you still use this command, please add an extra
option, '--i-still-use-this', on the command line
and let us know you still use it by sending an e-mail
to <mailto:git@vger.kernel.org>.  Thanks.
fatal: refusing to run without --i-still-use-this

use-commit-times.ps1:

#use-commit-times
[string[]]$changes = &git whatchanged --reverse --pretty=%at
$mtime = [DateTime]::Now;
[string]$change = $null;
foreach($change in $changes)
{
    if($change.Length -eq 0) { continue; }
    if($change[0] -eq ":")
    {
        $parts = $change.Split("`t");
        $file = $parts[$parts.Length - 1];
        if([System.IO.File]::Exists($file))
        {
            [System.IO.File]::SetLastWriteTimeUtc($file, $mtime);
        }
    }
    else
    {
        $mtime = [DateTimeOffset]::FromUnixTimeSeconds([Int64]::Parse($change)).DateTime;
    }
}
