New Revision: 324528
URL: https://svnweb.freebsd.org/changeset/base/324528
Log:
The th_bintime, th_microtime and th_nanotime members of the timehand
all cache the last system time (uptime + boottime). Only the format
differs. Do not re-calculate the bintime and simply use the value
used to calculate the microtime and nanotime.
Group all the updates under the relevant comment. Remove obsoleted
XXX part.
