If it's not one system, it's another. As I said, you (the collective you - your organization) _chose_ to use UTC. The need to maintain both UTC and TAI, and deal with leap seconds, is purely an issue internal to your organization. Perhaps your users have a real need for time closely correlated to UT/GMST, in which case stopping UTC leaps seconds would do them a disservice. You're trying to make UTC into something it isn't.
