WebCore/page/Timing.cpp:84
 +      return static_cast<unsigned long long>(domainLookupStart * 1000);
nit: use 1000.0 to improve readability (same nit applies elsewhere).  a
static helper function might also be nice: toIntegerMilliseconds(double)?

Wow, that is so much cleaner. Thanks.

Note: toIntegerMilliseconds probably would have been better as a file static instead of a class static.  that way it will have internal linkage and be optimized away to nothing (although that might still happen in this case).  class statics have external linkage by default.

Great education for me. I assumed they would compile to the same thing.

I'll post a follow-up patch.
