Dealing with no RTC and Appdaemon tasks

Hi All,

Been using appdaemon/Ha for sometime and for all accounts works superbly.
Anyway had the odd RP3 die (and more recently SD cards are failing which I suspect due to wear them out) made up several spares nearly two years ago to deal with these suitation.

On replacing these boards which also have a prebuild HA/ApD ready to go, were last switched on in 2017!!.
When the time does get synced, AppDaemon has two years of tasks to catch up on, which understandbly bogs down the system.
Short of installing RTC clocks or updating the dates before deploying them, any suggestion programatically on how I could deal with this?
