ae017078c9 Fix Posix::time_zone for southern hemisphere 
* The get_info functions were not prepared for the case where the start
  and end times of a rule are chronologically reversed for a year.  I.e.
  the daylight saving start comes later in the year than the daylight
  saving end.  When save is positive, this happens in the southern
  hemisphere (e.g. "Australia/Sydney" -> "AEST-10AEDT,M10.1.0,M4.1.0/3").
  It also happens in the nothern hemisphere when the save is negative
  (e.g. "Europe/Dublin" -> "IST-1GMT0,M10.5.0,M3.5.0/1").

* Added tests for Posix::time_zone.

018a50bcd0 Work around for a NVCC compiler bug 
The NVCC compiler fails to compile the date library due
to a compiler bug which causes it to emit an error when
directly using std::ratio_{multiply,divide} in the template
instantiations for std::duration. This PR works around the
issue by introducing custom ratio_{multiply,divide} which
delegate to the standard library templates

5ba1c1ad85 HAS_UNCAUGHT_EXCEPTIONS definition. 
Added some flexibility for usage of std::uncaught_exceptions().
Xcode 10 uses clang and perfectly compiles C++17, but
std::uncaught_exceptions() is available only on iOS 10+ devices. When
application supports iOS 9 devices and uses C++17 there is no way to
build it, except drop iOS 9 support or remove C++17 code. Using this
define we could configure should date.h use std::uncaught_exceptions()
or not.
