339  * We want to do realistic conversions of time so we need to use the same
345  * constants and so are computed at compile time.  SHIFT_HZ (computed in
362  * might calculate at compile time, however, the result will only have
377  * to capture as much precision as possible.  At the same time we don't
391  * 64-bits to get the full range time in nanoseconds.
435  * Convert various time units to each other:
493  * @m:	time in milliseconds
545  * @u:	time in microseconds
