    PPS. The ITU-G8271-Y.1366 time message itself output by Meinberg clocks is always a sequence of 21 bytes. While the standard briefly references the use of two ASCII characters for the first two characters, it should be noted that this message is not an ASCII string in the typical sense.

    In addition to these general-purpose time signals, there are other codes in use designed for specific appli- cations, among them NASA36, XR3, or 2137. The GPS/PPMOS-3/DAHS, however, limits itself to the output of IRIG-A, IRIG-B, AFNOR NF S87-500, and IEEE 1344 formats, as well as IEEE C37.118, the successor to IEEE 1344.
