The POSIX CLOCK_MONOTONIC currently has only 1/HZ resolution. 
Further, it is tied to jiffies (i.e. is a restatment of jiffies) 
rather than "xtime" or the gettimeofday() clock.

This patch changes CLOCK_MONOTONIC to be a restatment of 
gettimeofday() plus an offset to remove any clock setting activity 
from CLOCK_MONOTONIC.  An offset is kept that represents the 
difference between CLOCK_MONOTONIC and gettimeofday().  This offset is 
updated when ever the gettimeofday() clock is set to back the clock 
setting change out of CLOCK_MONOTONIC (which by the standard, can not 
be set).

With this change CLOCK_REALTIME (a direct restatement of 
gettimeofday()), CLOCK_MONOTONIC and gettimeofday() will all tick at 
the same time and with the same rate.  And all will be affected by NTP 
adjustments (save those which actually set the time).
