336  * We want to do realistic conversions of time so we need to use the same
342  * constants and so are computed at compile time.  SHIFT_HZ (computed in
359  * might calculate at compile time, however, the result will only have
374  * to capture as much precision as possible.  At the same time we don't
388  * 64-bits to get the full range time in nanoseconds.
432  * Convert various time units to each other:
490  * @m:	time in milliseconds
542  * @u:	time in microseconds
