Get Firebase Timestamp

I want to know how can I get the value of the timeStamp from the

, directly from the HashMap? I know that when that value is sent to Firebase I get the long value, but I want to get that long before send it to Firebase.

Answer Source

Okie so after some research I found that we cannot use ServerValue.TIMESTAMP before sending it to database because

ServerValue.TIMESTAMP is set as a Map (containing {.sv: "timestamp"}) which tells Firebase to populate that field with the server's time. When that data is read back, it is the actual unix time stamp which is a Long.


By the way you can use android own timestamp and store it in Firebase.

            Calendar cc = Calendar.getInstance();
            Date date = cc.getTime();
            // SimpleDateFormat format1 = new SimpleDateFormat("dd MMM");
            SimpleDateFormat format2 = new SimpleDateFormat("yyyyMMddHHmmssSSS");
            timestamp = format2.format(date);
