We should follow the Google C++ coding guide here because the timestamp doesn't
always return the same value:
https://google.github.io/styleguide/cppguide.html#Default_Arguments

Probably defining this as:

Event(const AtomicString& type,
      const EventInit&,
      TimeTicks platform_time_stamp);

Event(const AtomicString& type,
      const EventInit& init)  : Event(type, init, TimeTicks::Now()) {
}

is likely best.

Done.
