There has to be a space after the first line AND AFTER THE SECOND LINE.  And the time stamp starts when the key chain camera is powered on with this file on the root – not when the file is created – so create it with a time a minute ahead and then disconnect it from the USB (the proper way) and power up the keychain cam at that time.
