Read mach-o/loader.h. Step through the load commands, starting just after the mach_header (or mach_header_64).

The total size of all * of the commands is given by the sizeofcmds field in the mach_header. All * load commands must have as their first two fields cmd and cmdsize. The cmd * field is filled in with a constant for that command type. Each command type * has a structure specifically for it. The cmdsize field is the size in bytes * of the particular load command structure plus anything that follows it that * is a part of the load command (i.e. section structures, strings, etc.). To * advance to the next load command the cmdsize can be added to the offset or * pointer of the current load command. This email sent to site_archiver(a)lists.apple.com

It's 2038, not 2048. See <http://en.wikipedia.org/wiki/Year_2038_problem > 2. Your suggestion would blow away compatibility with every shipping application that measures time in seconds instead of minutes. 3. It's already fixed in the 64-bit libraries. time_t on 64-bit will not become a problem for the next 292 billion years, by which point you probably won't be using the computer you're currently using...
