Error 2038 Adobe Digital Editions Mac OS And Most

Old 32-bit apps might still run on newer systems. Also, 64-bit apps might contain coding mistakes or outdated designs, causing them to convert a 64-bit timet to 32 bits.

In fact, the Mac OS and most Mac applications can handle internally generated dates correctly all the way to the year 29,940.

Does this mean that any version is vulnerable to the Year 2038 problem, a problem comparable to the Y2K problem that affects Unix-like systems Or does the statement Apple gave about being compatible to the year 29,940 still hold true.

Regardless, Im still curious about if this statement that Apple made about Macs being compatible to the year 29,940 still applies to OS X, given that other Unix systems have problems with dates after the year 2038.

Apple has become slightly more aggressive regarding obsolete machines (optimization of chargers etc) to force its users upwards.

One way to know is to change the date on your computer to 2038.

Most installs of 10.6 and all installs of 10.7 Lion fixed the main cause of the problem.

Its almost gone, but the year 2038 bug might survive in a few apps.

BSD has a long history and some of its system calls come from the 1980s.

One of its system calls is gettimeofday(), which first appeared in 4.1cBSD.

UC Berkeley released 4.1cBSD in 1982, more than half a century before 2038.

It counts seconds, where zero is the Unix epoch of 1970-01-01 00:00:00 UTC.

A signed 32-bit timet has a range of -2147483648 to 2147483647.

This can only hold times from 1901-12-13 20:45:52 UTC to 2038-01-19 03:14:07 UTC.

When this overflows, gettimeofday() will flip the date from Monday the 19th of January 2038 to Friday the 13th of December 1901.

For OS X, this transition happened along with another transition from 32-bit pointers to 64-bit pointers, but 64-bit pointers require a 64-bit processor.

It is possible for 32-bit processors to handle 64-bit timet, but Apple never provided that feature.

In Unix and BSD, offt is the size of a file, or an entire disk.

Apple defined offt as 64 bits, so OS X worked with larger disks.

Apple defined timet as 32 bits in 10.0, so a transition to 64-bit timet needed to happen later.

Beginning in v10.6, applications that ship with the operating system are generally 64-bit applications.

I know from Wikipedia that 10.6 required an Intel processor and 10.7 required a 64-bit Intel processor.

A Mac running 10.6 on a 32-bit Intel processor must have had 32-bit apps.

I conclude that most Macs running 10.6 and all Macs running 10.7 have 64-bit apps with 64-bit pointers and 64-bit timet.

Old 32-bit apps might still run on newer systems.

Also, 64-bit apps might contain coding mistakes or outdated designs, causing them to convert a 64-bit timet to 32 bits.
