Following code for set data on firebase database.
I want to know how to get successfully saved details after set in firebase?

 //get current time fire base

  getCurrentDate() {

    //Client Meeting model

    let oCurrentDateModel = new current_date_model();

    oCurrentDateModel.current_date_time_stamp = firebase.database.ServerValue.TIMESTAMP;



    return new Promise<any>((resolve, reject) => {

      this.oAngularFireDatabase.database.ref('/Settings')

        .child('CurrentDate')

        .set(oCurrentDateModel)

        .then(

          data => {



            //THIS DATA IS UNDEFINED

            //HERE I WANT TO GET SAVED current_date_time_stamp



            console.log(data);

            //Alert Generation

            this.oAlertProvider.showAlert('Success', "Updated Successful");            

          },

          err => {

            reject(err);

            //Alert Generation

            this.oAlertProvider.showAlert('Error', err.message);

          })

    })

  }

To get the value of a server-side timestamp, you will have to attach a listener:

let timestampRef = this.oAngularFireDatabase.database.ref('/Settings/CurrentDate/current_date_time_stamp');

let timestampListener = timestampRef.on("value", function(snapshot) {

  if (snapshot.exists()) {

    console.log(snapshot.val());

    timestampRef.off("value", timestampListener);

  }

});

This snippet of code also removes the listener once it has gotten the timestamp value.
