sent at 9600 baud sets the time to 00:07:08 (and, presumably, the calendar to 25/5/12 though we don't know how to display that at the moment). The tailing 3D is a checksum - the 2-digit hex representation of the XOR of all previous characters, starting with the '>'.

The clock seems to initially set itself up for 19200 baud serial port but later in the initialisation changes it to 9600.
