If you want to project something beyond 9999-12-31, you can do that with custom timestamps, e.g. by specifying the year as a float. There's no need to convert that back to a timezone or sync it to UTC. The maximum difference of 1 day would be 0.00003% in 10K and decreasing, a level of accuracy no simulation can ever achieve.
