Hi Dean,
You can see what FreeBSD (pfSense) is using to keep time with the
following command:
firewall:~# sysctl kern.timecounter.hardware
kern.timecounter.hardware: TSC
You can see what is available with the command:
firewall:~# dmesg | grep Timecounter
Timecounter "i8254" frequency 1193182 Hz quality 0
Timecounter "TSC" frequency 499904486 Hz quality 800
Timecounters tick every 10.000 msec
You can try one of your other options with this command (e.g., to try
i8254):
sysctl -w kern.timecounter.hardware=i8254
If it keeps better time, you can add a line to /etc/sysctl.conf (so a
reboot will use your new choice):
kern.timecounter.hardware=i8254

i did the command you said ntpdate pool.ntp.org. and yes it sets
the time, but it doesn't stay. for long.
computer kept near perfect time before under different o/s. this
seems real strange.
Sounds familiar. I've seen and/or heard of this under 3
circumstances.
1) Buggy BIOS - I've redeployed older hardware that ran fine for
years
with Windows, but as soon as I redeployed with FreeBSD, it wouldn't
keep time for anything. Updated to the latest BIOS and the problem
was
gone. It was several revisions out of date, one of which included a
timekeeping fix that apparently didn't apply to Windows. I
specifically saw this with Dell hardware, but it's possible with any
hardware and have heard of others seeing the same with other
hardware.
2) PNP OS turned on - if PNP OS is on in your BIOS, turn it off.
3) ACPI issues - try disabling ACPI, sometimes it causes time
keeping issues.
