I'm running ubuntu as a domU on Xen 3.03... Within the dom0, date works as expected (returns the date, no jumps, monotonic increasing). On this particular domU, six consecutive calls to date would return the following: jpetersen@devel:~$ date Tue Dec 11 12:16:46 CST 2007 jpetersen@devel:~$ date Tue Dec 11 12:17:12 CST 2007 jpetersen@devel:~$ date Tue Dec 11 12:16:48 CST 2007 jpetersen@devel:~$ date Tue Dec 11 12:17:15 CST 2007 jpetersen@devel:~$ date Tue Dec 11 12:16:51 CST 2007 jpetersen@devel:~$ date Tue Dec 11 12:17:17 CST 2007 The calls were each made one second apart. (I'd script this using "sleep" within a loop, but the behavior I'm demonstrating breaks sleep). No clue why this is happening; the domU is not running NTP and independent wallclock is turned off (the dom0 is running ntp for me). This is breaking my build system, so any help would be appreciated. I've tried running ntp in the domU (with an independent wall clock), but have the same problem.
