I do think that the problem would not occurs if you enable APM in the 
kernel because with APM enabled, system time (i.e. time maintained by
the kernel) is resetted after a RESUME. 
If you do not want to enable APM in the kernel, a quick fix would be to
comment the line:

hwclock --systohc $GMT

in /etc/init.d/hwclock.sh

My decision would be to enable APM unless you have specific problems
with it.
