Your plan to use a Ds3231 chip and have the Pi shutdown automatically sounds good.
I don't know of any other way to keep accurate time on the Raspi.
The RTC information I sent you a link for in an earlier post is old and I have been working on new instructions for using an RTC with the newest raspbian versions (Jessie or Stretch).
I don't know your location or what access you have to electronic components but there is a nice RTC that is designed specifically for the Pi from Adafruit:
https://www.adafruit.com/product/3386
You just need to get it with the battery and plug it on to the Pi's GPIO pins (pins 1 to 6). It will work with the relay_16 SIP plugin.
I will post here as soon as I have the new instructions ready.
