lgtm

please change the title to refer to https://crrev.com/336230, which is the
commit associated with that review.  A codereview link won't uniquely identify a
commit in general as reverts show up on the codereview (and sometimes relands
too, which adds even more ambiguity).  The commit position is stable.

https://codereview.chromium.org/1287103004/diff/1/mojo/converters/input_event...
File mojo/converters/input_events/input_events_type_converters.cc (right):

https://codereview.chromium.org/1287103004/diff/1/mojo/converters/input_event...
mojo/converters/input_events/input_events_type_converters.cc:281:
base::TimeDelta(), // CAS time
what's CAS time? could you expand the comment a bit or have a link to somewhere?
