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.

83c8b4d522 changes for compatibility with Clang with Microsoft CodeGen (v140_clang_c2): 
- added date:: namespace to flloor() and abs() calls
- added IUnknown forward declaration before including Windows headers to prevent issue with objbase.h

44f6dfc58e fix compile warning about unused get_download_gz_file() 
get_download_gz_file() is not used when HAS_REMOTE_API=0, and causes:

warning: 'std::__cxx11::string date::get_download_gz_file(const string&)' defined but not used [-Wunused-function]

Wrap get_download_gz_file() inside #ifdef to remove the warning.

c64d69b1e1 Avoid getting localized time zone names from Windows OS. 
* Use GetDynamicTimeZoneInformation to get .TimeZoneKeyName
  https://msdn.microsoft.com/en-us/library/windows/desktop/ms724318(v=vs.85).aspx
  > Retrieves the current time zone and dynamic daylight saving time settings.
  https://msdn.microsoft.com/en-us/library/windows/desktop/ms724253(v=vs.85).aspx
  > The name of the time zone registry key on the local computer.

* This avoids the need to map from StandardName to TimeZoneKeyName.

* Using .DynamicDaylightTimeDisabled = true forces the OS to return a
  non-daylight saving time result.

* Use of wcstombs is preferred over wstring_convert as the latter is now
  deprecated in C++17 because the implementors could not interpret the
  specification.

c21e392c81 Initial Win32 support. 
This library now compiles on Windows but requires VS2015 for Windows.
VS2013 may work but this has not been tested yet.
Requires NOMINMAX to be defined to avoid clashes with the Windows.h
headers and the C++ stl and this libraries Date max functions.
Also known to work equivalently with recent g++ and mingw combinations
but -std=C++14 flag should be set.
C++14 restrictions may be relaxed later. Patches welcome!
g++ 5.1 was tested. It may work with other version but that hasn't been tried.
Mac OS and Linux systems are known to compile with -std=c++11
current_timezone and locate_zone will return iana names not windows
time zone names. This is expected and as designed.
