2 Problems : Timezone & AP mode

[belu40]

Hello! i read a lot of closed and solved issues but i didn't understand well how to solve 2 main problems that i have with AutoConnect. I state that i think this is a great library and permits to have an easier life using esp modules! But i still have some question for Hieromon and the comunity... In my project (code below) i started from the Simple example from Hieromon with connection to NTP server and made some tests...

problem1: I need to save the timezone setting made on the timezone page to reload the same setting after shutting down my esp32 and repower it. Now i found that the timezone setting is lost every time the esp is shutted down. (the dates and time that i see in my main page of the browser shows a date and time around 1970 after every restart. I made some tests to create a txt file saved with spiffs with the timezone configuration and try to read it at every restart but with no success( see code below)

problem2: I have problems with the access point mode. When i first power on ESP32 after programming it, it's correctly configured as access point and with a mobile device a set the correct information (settings) of my wireless network. Then when the network is not available anymore i need to get the access point mode working again after a set timeout but i can't get this working. I tried also to change the autoReconnect option from true to false but didn't understood well how this function works.

I hope to solve this! Thank you in advance! below the code!
