Net time command on CF.NET?

Hi all,

Due to network security restrictions, we can only ping time servers on our
subnet via its hostname (rather than by IP address) by issuing the command
in the cmd prompt:

net time //computername

Can we somehow emulate this in CF.NET? What time sync support does CF.NET
provide? Any example code to be shared? Thanks for any help or suggestions
you can provide bearing in mind this "locked down" network.

What version of the OS are we talking about? If CE.NET and if the time
service is running, you can send a DeviceIoControl() to the time service to
tell it to sync. I'm not sure if you can specify a server with a name that
isn't resolvable via DNS, though. At least, the time service is calling
gethostbyname() with the name specified in the registry...

Oh sure, there's already one out there! Time to put my code away...

This is PPC 2003. Is there any way to leverage the FTP protocol to do this?

the one suggested by Ilya is a good start but you will need to change from
udp to tcp if you want to sync time via active sync. also this is not an
async call and there is no timeout so it ends up hanging if the server is
not found.

send me an email if you want my adaptation of the code to make async.
