Ah - no. Simple like that. No NTP support.

You can use third party NTPClient.cs.

Example how to use:

DateTime time_nist_gov = NTPClient.GetTime().TransmitTimestamp; // uses NTPClient.DefaultTimeServer = "time.nist.gov"
DateTime time_windows_com = NTPClient.GetTime("time.windows.com").TransmitTimestamp;
DateTime pool_ntp_org = NTPClient.GetTime("pool.ntp.org").TransmitTimestamp;
