    22  Package mclock is a wrapper for a monotonic clock source.
    23  
    24  mclock package provides a Now() function which returns the current time in nanoseconds from a monotonic clock in Duration type.
    25  The returned time is based on some arbitrary platform-specific point in the
    26  past.  The returned time is guaranteed to increase monotonically at a
    27  constant rate, unlike time.Now() from the Go standard library, which may
    28  slow down, speed up, jump forward or backward, due to NTP activity or leap
    29  seconds.
