To keep track of time while the ESP32 is unpowered, add a DS3231 RTC chip with its own battery.

Update the time automatically when the webform is submitted.

I have the RTC module talking to the ESP32 and a way to fill in the unix timestamp in the webform, but the timestamp is from when the page was loaded, not when it was submitted.

get js timestamp on form submit, not page load
update RTC time from webform timestamp

I think we can do time with onsubmit: https://stackoverflow.com/a/33102497/2152245

var putDate = function(form) {
  form.date.value = new Date().toString();
};

<form name="test" method="post" action="B" onsubmit="putDate(this);">
  <input name="text" type="text" />
  <input name="date" type="hidden" />
  <input type="submit" value="Submit">
</form>

Trying to convert from string to long, it should work with new build flag but it's not.

I thought the issue was string conversion, but what has been causing the crash is
rtc.adjust(DateTime();, no matter what value is in it (or empty).

Functions in RTClib I can use: https://adafruit.github.io/RTClib/html/class_r_t_c___d_s3231.html

Calling RTClib as a dependency as the GitHub url in platformio.ini file. It is a newer version (2.1.2) than the library in PlatformIO/VSCode.

That seems to work.

~~why does it seem like webform files are being written twice? Javascript?~~ not doing it anymore
make it clear that this is UTC time!
get the time back to show it on the web page
- started, will test tomorrow

This makes it crash:
rtc.now().toString("DDD, DD MMM YYYY hh:mm:ss");

This makes it crash: `rtc.now().toString("DDD, DD MMM YYYY hh:mm:ss");`

Had to use rtc.now().timestamp() to get string rather than char. 🙄
