5.4.14.3 Format BBC-03 PSTN

The third format is a string ASCII characters and is sent on a received character.
The message should be advanced by an appropriate number such that the stop
bit of each <CR> occurs at the start of the next second. For example, at 300 baud,
8 data bits, 1 stop bit, and no parity, each byte takes 10/300 s=33 ms, so the <CR>
byte should be advanced by 33 ms in order for the <CR>'s stop bit to line up with
the start of the next second.
Time information is available in UTC format or UK TOD format.
