While you are using any other apps, to create a date-and-time stamp, 1. Just go the Notification Drawer, and tap the AutoHongKong notification. Then, this app will create a data-and-time stamp in the clipboard and return to the original app you have been using. 2. So you will be able to paste the date-and-time stamp in that app in this format: 2014-05-21 06: 03: 14 PM.
