Author: phk

New Revision: 1668

Modified:
   trunk/varnish-cache/include/libvarnish.h
   trunk/varnish-cache/lib/libvarnish/time.c
Log:
Add TIM_mono() and TIM_real() which return double representations of
timestamps on a monotonic and the UTC timescales respectively.

Doubles are much more convenient than timespecs for comparisons etc.
