Saving and retrieving date in Firebase

Question

I have a model with the following structure

public class OfferModel {
    private String mImageUrl;
    private String mOfferCode;
    private String mOffe         


        

Answer 1

Use ISO 8601 date format:

SimpleDateFormat ISO_8601_FORMAT = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:sss'Z'");

String now = ISO_8601_FORMAT.format(new Date());

Representing Date as a String has two greater advantages:

• It is human readable ("2018-03-30T13:18:39.516Z" vs 1522415925281)
• At the browser side, you can simply invokes new Date("2018-03-30T13:18:39.516Z")

This is quite useful if you have Android and browsers both consuming Firebase data.
