Remove BuildTimeUTC
I don't think I ever found it useful. It only adds burden IMO.
@nohwnd Aside from the failures in CI caused by MissingMethodException for the removed API (because we use last MSTest from test-tools but we use MTP from the current build), are you generally okay with this change?
Yes it is fine for me, I was not even aware of it being there, and there is no motivation in the original issue to include the time, so it was not a customer asking to do this.
Context: the goal was to provide some kind of incentives for people to notice that their platform is old and they should probably be looking for a new version.
Closing stale PR.
