Portability problems not fixed by Gnulib:
|
|
@itemize
|
|
@item
|
|
The Windows C runtime library (which is used by MinGW) does not
|
|
support the %e specifier (and possibly the other more recent SUS
|
|
specifiers too, i.e., %C, %D, %h, %n, %r, %R, %t, and %T).
|
|
@item
|
|
Native Windows platforms (mingw, MSVC) support only a subset of time
|
|
zones supported by GNU or specified by POSIX. @xref{tzset}.
|
|
@end itemize
|
|
|
|
Extension: Gnulib offers a module @samp{strftime} that provides an
|
|
@code{nstrftime} function with various GNU extensions.
