func NanoTime ¶

func NanoTime() int64

NanoTime returns the current time in nanoseconds from a monotonic clock. The time returned is based on some arbitrary platform-specific point in the past. The time returned is guaranteed to increase monotonically at a constant rate

This can be use for performance critical code where getting the wall time can slow down execution.
