The 8 bytes represents the 64 bit raw value of the Real Time Clock register. The data is appended
before calculating TCP checksum so it will pass thru the TCP stack correctly. This register counts at 32,768
Hz. If the timeserver function is enabled, the RTC should accurately reflect the real time. This register is
also counting while in sleep mode.
