8b9f0515b5 Replacing 0 with nullptr to avoid GCC warning 
All the calls to `std::time_get::get` had `0` as end-of-range iterator.

E.g.

    auto& f = use_facet<time_get<CharT>>(is.getloc());
	// ...
    f.get(is, 0, is, err, &tm, command, fmt+1);
              ^

Using `nullptr` instead of `0` doesn't trigger the GCC 5.x warning:

> warning: zero as null pointer constant [-Wzero-as-null-pointer-constant]

2032fccbb7 Fix valgrind warning about uninitialized variable use in to_stream() 
tm variable is not initialized in to_stream(), and valgrind warns about
"Conditional jump or move depends on uninitialised value(s)".

This is a false positive, as strftime always reads tm_hour, even if it
ends up never using it. To silence the warnings, initialize tm to zero.

a610f087c1 Add support for the zic-compiled OS-supplied time zone DB: 
*  Avoids the need to download the IANA database.

*  Heavily based on contributions by Aaron Bishop.

*  Turn on with -DUSE_OS_TZDB, off by default.

*  Not supported on Windows.

*  Disables HAS_REMOTE_API.

*  get_tzdb().version only supported on Apple.  This string has
   the value "unknown" elsewhere.

*  Leap second support is missing on Apple, and may not be on your
   platform either (please report).  Leap second support is enabled,
   disabled with -DMISSING_LEAP_SECONDS.

   Without leap second support, utc_time, tai_time, and gps_time (and
   those clocks) are not available.

*  On Apple, time zone transitions are only supported in the range:

   1901-12-13 20:45:52 to 2038-01-19 03:14:07

*  On Linux, time zone transitions are only as far in the future as
   the OS-provided transitions go.  There is no support for POSIX-
   style transitions.
