Hello - new to the list here.
I am developing a c# (.net) class to encapsulate the TSIP protocol. An issue
I ran across is how to accurately sync the system time running Windows with
the time packets from a Thunderbolt. I've noticed that setting the OS system
time with the time indicated in the TSIP primary timing report can create a
noticeable accuracy difference between a PC's system time if not biased.
I've compensated for that using a difference in Tick counts from the system
and the time value reported by GPS. Here is the relevant code:
current_time = new DateTime(stime.Year, stime.Month, stime.Day,
stime.Hour, stime.Minute, stime.Second);
DateTime d = DateTime.Now;
// set system time once each minute if desired
if ((set_system_time) && (stime.Second == 0))
{
long td = (current_time.Ticks - d.Ticks) / 1000000000L;
stime.Milliseconds = (short)td; // advance the clock by diff in
tick count
Win32.SetSystemTime(ref stime);
}
My question to the list is: Does anyone have experience with this issue and
a better solution?
Thanks in advance,
Dan Quigley (N7HQ)
