    Does your machine have a history of problems keeping time or is this
    something new?  Have you changed your video settings or operation 
    recently?... video bioses are known to mess up 8254 based timing
    (which also means you are running without ACPI).  What kind of machine
    is it?

    It kinda sounds like the bios is interfering with the 8254, and not
    something broken with dntpd.  If that is the case then you can tell
    the kernel to use a different 8254 timer with:

    hw.i8254.walltimer=1

    in your /boot/loader.conf.  Sometimes this works, sometimes this
    locks up the box.  If it locks up the box you will have to reboot,
    break out of the boot menu and unset the variable in the loader before
    booting so you can boot your kernel and then remove the line.
