Description Nathan G. Grennan 2001-11-14 08:27:52 EST

User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.5+)

Description of problem:
I had upgraded by bios and cleared it with the jumper. I forgot to reset
the clock and ntp didn't reset it because the difference was over 1000
seconds. When untaring a file I got alot of error message about future
dates and figured out I had forgot to set the time. So I used ntpupdate
servername  and updated it. I have done small changes before to test ntpd,
say by changing the clock by 10 minutes. When I currented the time it would
start the screen saver, naturally. This time it crashed all of X and I got
dropped back at the gdm login prompt.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Set clock way back, ie. Jan 1 1970 1am
2. Start X
3. Set time to current time


Actual Results:  X crashs

Expected Results:  Programs to update, maybe the screensaver to come on if
it is running, but not for X to crash

This bug was just fixed I believe, and is in the current Rawhide
version of X 4.2.0-6.45, and also in 4.1.0-23 which is soon to be
released as erratum.  It was fixed by Chris Blizzard and Keith
Packard, and was due to a time wraparound bug in xdmcp.c
