Attached an example how to get the time form a NTP server.

Find source attached, comments are included.

If you want to run the code please modify the APN in regards to the used SIM/MNO

 sntpclient.setApn("apn of your mobile operator");   (IMlet.java  - line 22)

If needed setters for username and password are available in the SntpClient.java object as well.
