`time.Now()` uses the wall-clock and therefore calling it twice, one second apart, can produce quite different results (negative results but also a difference greater than one second). Go doesn't expose a monotonic clock, therefore, it's difficult to properly fix (but there is https://github.com/gavv/monotime if we want a proper fix for `timer.Time()`). This workaround just discard any negative duration.

time.Now()uses the wall-clock and therefore calling it twice, onesecond apart, can produce quite different results (negative results but
also a difference greater than one second). Go doesn't expose a

There are other places that incorrectly uses
time.Now(). I can add a similar check or I can importmonotimeto properly fixes them.
