you should get blocked for requesting every 30sec on any serious ntp server ...

Time sync should happen at most once per hour. And that is overkill.

I should have said unsigned int instead of long int.

The NIST site says requests more frequently than every 4 seconds may be blocked. The reason I was requesting so often was that is was difficult to time my loop and the time was drifting using the delay() function. I wasn't familiar with the millis() function until yesterday. I am now using that function and making a request much much less often. No matter what the interval is that I use, someone will surely say it's too often, so I'll not say. Read the site at http://bit.ly/2XuUHuw. Near the bottom there is a mention of overflow.
