Portability problems not fixed by Gnulib:

• This function is deprecated in C23. Likewise, POSIX says this function is obsolescent and it is planned to be removed in a future version. Portable applications can use strftime (or even sprintf) instead. However, strftime is locale dependent.
• This function may overflow its internal buffer if its argument specifies a year before 1000 or after 9999. See ctime.
• Although it is tempting to call this function on the value that functions like localtime return, this is typically a mistake. On most current platforms, these functions return a null pointer for timestamps out of range, and this function has undefined behavior in that case.
