[time-nuts] GPS time, UTC and TAI

[mike cook]

Martyn,

for M2M the command to select either GPS or UTC time output is

@@AwmC<CR><LF>

   m=0x00 for GPS
        0x01 for UTC

C = checksum = XOR of all bytes after @@ and before the checksum

      for GPS  = 0x36
            UTC = 0x26               if my logic is ok
