The past couple of months, when the machine comes up from hibernation,
the clock is a few hours ahead. Now it's 4 hours ahead. It was 5 hours
ahead before the switch to daylight savings time. This looks
suspiciously like GMT. GMT is 5 hours ahead of EST, and 4 hours ahead
of EDT.
I dug deeper. Apparently, it's just the "kernel system time" that
gets bumped forward when it wakes up from hibernation. The BIOS clock
is OK. As a heavy-handed hack, I've inserted the line...
OnResume 01 hwclock --hctosys
...into my /etc/hibernate/hibernate.conf. This copies over the BIOS
time to the kernel system date. It works, but I'd really like to know
why it's necessary in the first place.
# hwclock --help
Gives many options to test.
