There's an interesting comment in /usr/lib/pm-utils/sleep.d/90clock
#!/bin/sh
# Synchronize system time with hardware time.
# Modern kernels handle this correctly so we skip this hook by default.
. "${PM_FUNCTIONS}"
suspend_clock()
{
/sbin/hwclock --systohc >/dev/null 2>&1 0<&1
}
resume_clock()
{
/sbin/hwclock --hctosys >/dev/null 2>&1 0<&1
}
So this would imply that at some point, the kernel did not handle this
correctly. Maybe there was a regression.
Just as a reference so that everyone reading this and setting this
option knows what they're doing to their system:
NEED_CLOCK_SYNC
If your system clock drifts across a suspend/resume or
hibernate/thaw cycle, you should set this to true. This will cause
pm-utils to synchronize the system clock whenever going through a
sleep/wake cycle at the expense of making suspend/resume take
longer.
