Description

The program should be able to get a valid time.

How to reproduce

Load the sample program...

It will attempt to get the time over 10 itterations before showing it is possible.

Expected behaviour

It should be able to do it on first attempt.

Aditional information

Given that the NetworkHelper is just a while loop checking for a DateTime with the year greater than 2023, this is to some extent expected. However, the check is too simplistic and needs to at least try and force a check, otherwise we might as well not have it!
