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.
