Firestore query by date range

Question

I need the help to query long collection with date range. See the below example document. I wanna query startTime field using date range.

Answer 1

The solution is to use Date.now (), stop using timestamp service from firebase, you need to work with the numerical value of the time in milliseconds like for example: 1514271367000, instead if firestore uses 26/12/2017 1:56:07 GMT- 0500 (-05) will not work. An example of a query is:

this.fsService.afs.collection('chats/4bY1ZpOr1TPq8bFQ3bjS/finance/123+finance/12345'
          , ref => ref.orderBy('hour').startAt(1514184967000).endAt(1514271367000))
          .valueChanges().subscribe(data =>{
            this.mensajes = data;
          })
