The internal RTC that the ESP32 uses is not accurate also there is no way to add an external battery to keep time. I'm going to add the DS3231 back in as an option for time if needed. I'm going to target the Adafruit https://www.adafruit.com/product/3013 since it's has many clones and is easy to get. This will be a requirement if you're going to use local zone schedules.
May use this as a way to wake the processor from a deep sleep state
