I think I found out where the problem is.
VxWorks doesn't have adjtime( ), and the one we wrote wasn't doing
anything. That's what makes the drift to increase to +500 (I think).
Does that make sense??
We would like to know what adjtime( ) actually does, so we can rewrite
it for VxWorks correctly.
Harlan,
I changed hz to 100 and ran it overnight yesterday. It seemed like it
had affect on the drift file problem, because normally the drift file
would have already been created after 10 hrs, and complained about 500
value in the drift file. But now the drift file still has not been
created yet,

I did that. But when I ran it overnight, the drift file with 500 was
created, (but the ntp was still running). Last time when I ran it for
3 days, the drift file had a value of -500 in the end, and ntp had
stopped sync-ing the clock on the clie

After I deleted the drift file and left it run overnight, the drift

If it is not, what other problem may it be? I saw someone in the forum

Dear all,
I'm very confused on how ntp do the timestamp. I'm running ntpd on
vxworks. It seems to me that the receive timestamp and the Transmit
timestamp are using two different clocks, because when I use ethereal/
wireshark to look up the information of the ntp packet,
the Recevie Time Stamp is:

After I "make" the ntpd, I found out the executable generated from
"make" can't handle datatype double. Whenever I printf or do any
caculation with double, ntpd will hang.
Then I wrote a simple hello world program to printf double, it also
hangs with regular gcc command.
For example:

Thank you everyone for the input. I know I suck. After all the advices
and suggestion, I think of two problems:
1.) VxWorks doesn't have getpagesize() or _SC_PAGESIZE, so basically I
just guess the value. I check the kernel configuration of the VxWorks,
and saw the VM page size is 4096. I "assume"
Basically, what i need is how to add to the ntp.conf to record
statistics. Thanks =D
