@item
This function is missing on some platforms:
FreeBSD 14.0, OpenBSD 7.5, Minix 3.1.8, AIX 5.1, HP-UX 11, Cygwin 2.9, mingw, MSVC 14, Android 9.0.
@item
On some platforms, this function does not support timestamps past the
year 2038:
glibc 2.38 on 32-bit platforms like x86 and ARM where @code{time_t}
was historically 32 bits.
@item
@mindex year2038
@mindex year2038-recommended
On some platforms, this function misbehaves if the @code{year2038} or
@code{year2038-recommended} modules are used and the program is
configured without the @option{--disable-year2038} option.
@mindex readutmp
The @code{readutmp} module works around this problem:
glibc 2.38 on 32-bit platforms like x86 and ARM where @code{time_t}
was historically 32 bits.
