Hi, I'm not a very experienced programmer so I hope I will be excused if this question seems stupid. I'm developing a network application and in the data packets I'm putting a time stamp. But from some tests I have made the best accuracy I can get from the GetLocalTime is 55ms I would like to have an accuracy of 1 ms. Any suggestions of how to do that. I'm using Visual c++ and a Windows95 PC when I'm developing this one. When doing a simple ping I can see response times of 1-3 ms, what is ICMP echo using to get that accuracy. Hoping for help.

Hi,
I'm not a very experienced programmer so I hope I will be excused if
this question seems stupid.
I'm developing a network application and in the data packets I'm
putting a time stamp. But from some tests I have made the best accuracy
I can get from the GetLocalTime is 55ms I would like to have an
accuracy of 1 ms. Any suggestions of how to do that. I'm using Visual
c++ and a Windows95 PC when I'm developing this one.
When doing a simple ping I can see response times of 1-3 ms, what is
ICMP echo using to get that accuracy.
Hoping for help.
