`performance.timeOrigin` was being set from when JS started executing, but `op_now` measures from an `std::time::Instant` stored in `OpState`, which is created at a completely different time. This caused `performance.timeOrigin` to be very incorrect. This PR corrects the origin and also cleans up some of the timer code. Compared to `Date.now()`, `performance`'s time origin is now consistently within 5us (0.005ms) of system time.  |
