[ros-dev] [ros-diffs] [pschweitzer] 64752: [NTFS] Implement NtfsDateTimeToFileTime() which convert epoch time (1970) to Windows time (1601)

[Pierre Schweitzer]

My link says: "Values are stored in universal coordinated time, like in
Linux."
This is what I interpret as: stored with epoch, need to shift to 1601.
