We have a check-in and check-out component in our web app that simply uses firebase timestamps. However, we need the ability to edit those timestamps in the event someone makes a mistake.
checkInTimeStamp: fb.firestore.FieldValue.serverTimestamp("17:00") simply returns the current time.
Instead of 17:00, what object do we need to pass through the function to get the correct timestamp?
The serverTimestamp() generates current timestamp on server side. You can use a Date object instead to store a future date:
const futureDate = new Date();
// update date to future time
futureDate.setDate(futureDate.getDate() + 5);
db.document('col/doc').set({ checkInTimeStamp: futureDate })
Checkout other method like setDate() in MDN docs.
