  • Guess you can reuse some 3rd party SNTP libraries. Googled?? – Zenwalker Jan 10 '12 at 09:03

    what do you want, it a bit unclear: the dateTime of the system or the dateTime of the internet? – Moonlight Jan 10 '12 at 09:03

The way you describe it's not so simple.

If you absolutely have synchronize system's time take a look at this project. It involves calling windows system api and I'm pretty sure you'll need high privileges to run that code.

If you just need to get time from the internet for your application this question has the answer for you.

I tried lot of solution's but the one below worked for me .

Process.Start("time", DateTime.Now.ToString());

just use Process Class and CMD to change the Time ,and i think you will need Administrator Privilege for that .

You can use this class to get the time from an NTP Server .
