> you definitely cannot rely on clocks to determine (reliable) ordering across machines
You can if you consider "unknown/possibly concurrent" also a valid outcome: for any 2 events A and B, True Time can definitely answers whether A is before B, A is after B, or A is possibly concurrent with B.

"reliable ordering" usually implies a specific and well-defined order, without concurrent events :)
