Description Wenson Hsieh 2021-10-06 09:58:00 PDT 
When computing time out deadlines for IPC messages, the time granularities (on the order of hundreds of ms) are many, many orders of magnitude greater than the granularity of ApproximateTime; this makes it much cheaper to use ApproximateTime instead of MonotonicTime when computing these deadlines, which significantly improves performance in the case where we're streaming high volumes of IPC messages.
