I assume the time-changed info is used by accounting programs.  Without that 
info, any accounting and possibly billing data for the time logged in will be 
off one way or the other if the time gets stepped while you are logged in.

Normally, time is only stepped when ntpd is first run at boot time, and even 
then it's often under a second.

You can test your system by grepping your /var/log/messages or 
/var/log/syslog for "clock_step".  Look in something like 
/var/log/ntp/ntpd.log if your ntp.conf puts logging in a separate file.

Joel says RTEMS doesn't support utmpx.h so I'll start by making that case 
build.

But you are right.  It was ifdefed out in ntp classic so I won't bother to 
recover the utmp (no x) case.

Does buildbot have an OpenBSD machine?

Do we have a way to test on RTEMS?
