When sleeping/in standby, the kernel isn't recieving timer interrupts,
and so the internal clock isn't being updated.  You can run a program
upon waking that resets it by reading the hardware clock, or if your
platform has an interrupt that is generated upon shutdown/waking, you
can take advantage of that to set up an automatic re-synch.  Our Mach
platforms use the former approach run as a background daemon, and our
NetBSD platforms will probably do the same.  Hardware independent and
all that.
