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.

1e7e7a214d Simplify the implementation of format and parse: 
* For format, all a type must do is implement to_stream.

* For parse, each type X must specialize parse_manip<X,CharT,Traits>.
  Each specialization must include a public typedef to itself named
  type.

* Each parse_manip specialization must have a stream extraction
  operator.

* This commit depends on expression-SFINAE.  If this commit breaks
  your build, it is likely that your compiler/version does not
  support expression-SFINAE.  To fix this NO_EXPRESSION_SFINAE
  needs to be defined in the configuration area of date.h for
  that compiler/version.

0cfa783b14 Unify and simplify fractional decimal seconds formatting 
* Many of the ideas and some of the code herein is credited to
  Adrian Colomitchi

* Decouple fractional decimal seconds formatting from time_of_day
  formatting so that it can be more easily used elsewhere in the
  future.

* Include super-second durations such as nanocenturies and
  microfortnights in the class of durations that will get formatted
  with fractional decimal seconds.

* If a duration is exactly representable with fractional decimal
  seconds not exceeding 18 decimal fractional digits, format it
  exactly.  Otherwise format it to 6 fractional decimal digits
  (microseconds precision).  The number 18 is chosen as this is the
  limit of std::ratio using 64 bits (i.e. atto).

* The above bullet implies that durations with ratio<1, 4> will now
  be formatted with 2 fractional decimal digits instead of 1.
  ratio<1, 8> will be formatted with 3, and ratio<1, 3> with 6.

* Unify the implementation into one C++11 implementation that works
  equally well with C++14.

* Drive-by fix a couple formatting bugs dealing with negative
  durations.

* Deprecate the make_time functions taking unsigned md by removing
  their documentation.  Also deprecate the corresponding time_of_day
  constructors taking unsigned md.

* This change paves the way for future formatting improvements.
