The official time of the US for commerce and legal purposes is UTC(NIST).
The official time of the US DOD is UTC(USNO).
The official time of the Federal Republic of Germany is UTC(PTB).

The CGPM recommendation on the timescale everyone should use says UTC.

UTC(insert your national time service here) is available in real time.

TAI is the mathematical (really the political or diplomatic) entity
upon which UTC is ostensibly based, but the practical and legal
reality is the other way around.
