Reproducible sample code

The following code is under .configure

PushNotification.configure({
onNotification: (notification) => {
PushNotification.localNotification({
              showWhen: true,
              title: notification.data.gcm_title,
              message: notification.data.message,
              userInfo: notification.data,
            })
}

@Dallas62 I have managed to get the timestamp appear! So the key is to pass new Date().getTime() to when field. We do not need the field usesChronometer, otherwise the timestamp will keep running like a stopwatch.

Thanks for your help! (:

Here’s the final look of the code

PushNotification.localNotification({
              showWhen: true,  // This is probably not needed, since default value is TRUE.
              when: new Date().getTime(),
              title: notification.data.gcm_title,
              message: notification.data.message,
              userInfo: notification.data,
            })

Yea, i notice that actually. But can you show me an sample value for when field? I tried to add 11:30 AM STRING earlier, didn’t work out.

Update 1.0

I think the timestamp value should be 1320917972 correct?

I actually dived into library by adding .setWhen(System.currentTimeMillis()) to NotificationCompat.Builderwhich end up like …

NotificationCompat.Builder notification = new NotificationCompat.Builder(context, channel_id)
                    .setContentTitle(title)
                    .setTicker(bundle.getString("ticker"))
                    .setVisibility(visibility)
                    .setPriority(priority)
                    .setAutoCancel(bundle.getBoolean("autoCancel", true))
                    .setOnlyAlertOnce(bundle.getBoolean("onlyAlertOnce", false))
                    .setWhen(System.currentTimeMillis());

but still result the same.
