De facto, the known magic numbers are those interpreted by the
Unix "file" command. There is a freeware version of this, which
seems to be the latest, at ftp://ftp.deshaw.com/pub/file .
The authors will accept magic number information in "/etc/magic"
format, which they will propagate into the next
release. A search of the current (3.22; January 1997)
version reveals no conflicts (no magic numbers with "TZ" in them).
The contact addresses given in the current version (3.22) are:
Christos Zoulas <mailto:christos at deshaw.com>
Mark Moraes <mailto:moraes at deshaw.com>
They want to get lines of the following form:
0 string \x14\x1aTZ compiled time zone information
0 string \x89TZ\x0d\0x0a\x1a\x0a compiled time zone information
I withdraw my proposal to insert a NUL into the magic number,
as this will cause "file" to malfunction. When this list has
settled on a magic number, ADO can drop them the appropriate
