The previous version "NTP_Web_Interface.ino" ran for several months with no issues; it was running ESP8266 version 2.3.0. This one is using ESP8266 version 2.4.1.
All that is produced by calling getDateTime function is"Thu Jul 13 02:38:21 2017." This is the first time I have worked with structures. What I find puzzling is "Time.ino" works producing updated date and time string. I took parts of Time.ino" adding variables to above setup, added "Time.ino" setup section to setup, added loop to new loop of my project. Created getDateTime function.
