        // NOTE: Java does not expose a nanosecond wallclock timer, like POSIX
        // CLOCK_REALTIME, only one like CLOCK_MONOTONIC. (Among other things, 64 bits is
        // only 292 years.) There is a tradeoff between using synchronized clocks in a
        // multi-node environment and using clocks that NTP doesn't change so that
        // small-scale deltas are always accurate.  fdbserver metrics choose the former.
