Hiya,

I do not think such a change would be a good idea.

If you did, then ISTM eventually nearly every BP node would need to
be able to understand and translate between every possible planetary
timescale. Sounds like a recipe for bugs and possible vulnerabilities
to me.

So, better for the lunar devices to translate to/from UTC when making
or reading bundles I think.

Cheers,
S.
