Why is this such a difficult thing to keep in sync? :(

I have a FreeBSD Host running 4.2.18 … Guest FreeBSD Host has Additions 4.2.18 
installed .. 

On the Host, I believe all the kernel modules are loaded properly:

# kldstat|grep vb
 6    3 0xffffffff80c59000 59da0    vboxdrv.ko
 8    2 0xffffffff80e20000 29f1     vboxnetflt.ko
11    1 0xffffffff80e2e000 3f8a     vboxnetadp.ko

On the Guest, again, I believe everything is loaded:

# kldstat|grep vb
 2    1 0xffffffff80c12000 26585    vboxguest.ko

And the VB processes are started:

# ps aux | grep VB
root      606  0.0  0.1  32244   2144 ??  Ss    6:06PM    2:09.26 
/usr/local/sbin/VBoxService

I don’t have ntpd running on the Guest, but have tried it with it running also 
...

But, my time is already drifting:

# ssh ruralcatholicradio.com date ; date
Wed Dec  4 12:01:34 EST 2013
Wed Dec  4 17:03:17 UTC 2013

So, I login and run ntpdate to bring it back in sync:

# ntpdate time.nist.gov
 4 Dec 12:04:02 ntpdate[71827]: step time server 66.219.116.140 offset 
102.233151 sec

Note that the below is run from the FreeBSD Host that the Guest is running on … 
same physical machine … we are perfectly in sync:

# ssh ruralcatholicradio.com date ; date
Wed Dec  4 12:04:32 EST 2013
Wed Dec  4 17:04:32 UTC 2013

An hour later, we’ve now drifted by almost 2 minutes:

# ssh ruralcatholicradio.com date ; date
Wed Dec  4 13:07:18 EST 2013
Wed Dec  4 18:09:16 UTC 2013


Its hard to believe that anyone would be using VirtualBox if it time drifted 
like this regularly, so I figure it has to be something that I’m doing wrong in 
my configuration …


Thoughts?

Thx
