above are my code . I'm using iPhone. My doubt was during I uploading the coding the hone page timer remain as 1970 year and the clock remain as 0h 0 second . Its that able to change it as a real time clock or UTC clock ?

[Hieromon]

Simple.ino as an example has two assumptions. One is that the ESP module was able to connect to the Internet, and the other is to display the time by reloading the web page manually. It's not a real-time clock sketch application.

This topic is not relevant to the improvement of the AutoConnect library but is maintained to clarify the Simple.ino example's intent.
