The warning reuses the uptime max of 30 years used by settimeofday(). Note that the warning is only emitted for writable filesystem mounts through the mount syscall. Automounts do not have the same warning. Print out the warning in human readable format using the struct tm. After discussion with Arnd Bergmann, we chose to print only the year number. The raw s_time_max is also displayed, and the user can easily decode it e.g. "date -u -d @$((0x7fffffff))". We did not want to consolidate struct rtc_tm and struct tm just to print the date using a format specifier as part of this series. Given that the rtc_tm is not compiled on all architectures, this is not a trivial patch. This can be added in the future.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
