Hi,

I need to contact a network time server via the NTP to synchronize the time.
Does anybody know about good products to do this?

Thank you

Why not simply use the net time command of the operating system?

Hi Thomas,

thank you for your answer, but I need to ask the time to a specific 
network time server using NTP.

Hi Thomas,

thank you for your answer, but I need to ask directly the time to a 
specific network time server using NTP.

That's what the time command can do, it sets the time and you can use
time() to get this (new) time - or do you want to avoid setting the local
time of the machine your program is running on?

Then you need to implement your own NTP client; probably by using ASINETs
low level socket functions.

Hi Thomas,

correct: I just want to know the time on a NTP server without changing 
the time of the local machine.
I know the NTP communication is via UDP, so, yes, if I will find no 
alternatives I will need to implement it.
