Domestic Ticket

Aztec barcode, in PDF or image
Variable length
For domestic tickets only, international ones use RCT2 in UIC 918.3 container
zlib compressed textual payload starting at offset 3.
zlib decompressed content is plain text and hardly larger than the full compressed data, which suggests the compressed data doesn't span the full length of the barcode (signature?).

34 lines, delimited by 0x0A
UTF-8 encoded
date/time format: 8 digits, the first 4 digits are the days since 2009-01-01, the last four are the time in "hhmm" format. Local time/no timezone.
