No, that was more like "Atlas replaces TTM, which had nice built-in
Stratum-1 clocks, and look, my Atlas Anchor could happily use those
leftovers from TTM to get great time!" - I found it amusing.

Seriously, with the measurements Atlas does, I expect precisely synchronized 
time between nodes to be much less relevant than for TTM - for one-way
measurements, it needs to be as precise as you can get, for "send a packet
and wait until the answer comes", having something in the 0.1 second
precision range strikes me as "good enough to find the measurement in
question in the log".
