Well, if we must have a standard, how about rather than simply using the
wiki definition of a DTG, we drop one step back for the non-NATO (and non-military) members of our audience and embrace the more universally accessible Wikipedia style guide for handling dates?

If you insist on using DTGs, knock yourself out. I understand the desire for consistency but two digit years have been out of favor since the run-up to Y2K, as indicated in
ISO 8601.
