问题 Currently, I have a firestore database set up with a users collection and a funkoPops collection. The funkoPops collections has about 750 documents which are genres/series of funko pops. So an example of one document would be, document.id = "2014 Funko Pop Marvel Thor Series 2 Vinyl Figures" and that document has fields of funkoData, and genre. funkoData is an array of objects that are the funko pops that are within that 2014 series as you can see here.

问题 Anyone knows how to persist UTC Timestamp in Firestore? In my Angular app, if I convert today's date to a Timestamp like the following and I end up with a UTC+2 (it's summer time here right now in Switzerland) date in the Firestore database import {firebase} from '@firebase/app'; import '@firebase/firestore'; const myTimestamp = firebase.firestore.Timestamp.fromDate(new Date()); If for example I try to convert a date from the winter time, I end up with UTC+1 Timestamp in the database const

问题 For my project I need ids that can be easily shared, so firestores default auto generated ids won't work.
