Richard's guess is a good one, but it might be a bit off in the details. It
depends a bit on what you mean by "back". I think he is right that the
hardware and software clocks have a mismatch, but I can't tell from what
you wrote which way the mismatch goes.
By convention, GMT (or UT) is 0, and EDT is -4 (4 hours earlier). If (for
example) you boot/init your machine at noon, and the time displayed is 8 AM
(this is what I would describe as "back by four hours"), then
your hardware clock is set to local time
your software clock thinks the hardware clock is set to GMT
In contrast, if (for example) you boot/init your machine at noon, and the
time displayed is 4 PM, then
your hardware clock is set to GMT
your software clock thinks the hardware clock is set to local time
You can get them beck into sync by changing either half.
To change the hardware clock, the usual tool is "hwclock". The
command "hwclock --systohc" will use the current system time (first reset
this using "date", or maybe KDE has some thingie to do it) to reset the
hardware clock.
To change what the software clock expects to get from the hardware
clock ... well, this part seems to be quite distro specific, so if you want
to do it this way, tell us what distro you are using. In Debian, for
example, all you would need to change is a line in /etc/defaults/rdS (a
line which says either "UTC=yes" or "UTC=no", recording which way the
hardware clock is set); "man tzsetup" for more details here (if you don't
use Debian, you might see if "man tzconfig" rerurns a man-page listing).
But I don't know how Debian-specific this approach is.
