Datetime to epoch int

[tgubler9]

Goals

• It should be easier to use just use an epoch int for the time. We will log information using the ISO 8601 string so that it is readable when needed.
• Reasons for this include storage decrease, sorting tables based on integers is faster (less cpu cycles), and our models are meant to able to just be plugged into the ddb put and get as there is data type checking with pydantic, but this becomes less usefull if we are converting data to primitive types before entering it into ddb.
