[time-nuts] 270 fs clock accuracy achieved at UCLA

The frequency relative uncertainty of the fully stabilized chip-scale
optical frequency comb is thus calculated at 2.7 × 10−16, referenced to
the 188-THz optical carrier.

I don't understand where your "270 fs" value in the post subject comes
from. The stated uncertainty is 2.7 × 10−16, which would be a time
relative uncertainty of 270 as (attosecond) over a one second interval.
