so you want to make a server, not use sntp() function as a client right?
have a look at RFC 2030
it explains how it works.
and/or show what you have so far.

Hello NE5660
As Mark said you have to read RFC 2030 https://tools.ietf.org/html/rfc2030
SNTP is not a function it is a time server just like a web server but you ask it for the time not web pages

mind you that this is the BASCOM forum and the ARDUINO is for the ARDUINO hardware.
This is not intended to discuss arduino or PI projects. there are a lot of other forums for that.

It is still not clear what the TS wants but it appears he want to make a time server. that is relatively simple. Just read the RFC !
