after the rising edge of 1PPS signal, and the
tramission is completed within 500 ms, as

indicates the time of the current 1 PPS rising
edge, and is sent at a rate of once per second.

TOD Frame
TOD messages use whole 8-bit bytes for
transmission, with check sum protection.
Message type and message ID are used to
clarify messages. Follows Big Endian
convention when a field is longer than one byte,
where bit 0 represents the least significant bit
(LSB), and bit 0 of each byte is transmitted first.
