Package mono provides a fast monotonic time. Its primary advantage is that it is fast: It is approximately twice as fast as time.Now. This is because time.Now uses two clock calls, one for wall time and one for monotonic time. We ask for the current time 4-6 times per network packet. At ~50ns per call to time.Now, that's enough to show up in CPU profiles. Package mono is a first step towards addressing that. It is designed to be a near drop-in replacement for package time.
