@node Avoiding the year 2038 problem
@section Avoiding the year 2038 problem

The ``year 2038 problem'' denotes unpredictable behaviour of programs
that will likely occur in the year 2038, for programs that use a 32-bit
@samp{time_t} type.  See @url{https://en.wikipedia.org/wiki/Year_2038_problem}
for details.

The gnulib module @samp{year2038} attempts to avoid this problem, by
ensuring that @code{time_t} is a 64-bit type.
