feedc0de/date: A date and time library based on the C++11/14/17 <chrono> header - date

T

Benno Evers 2acf403bcd Dont include ios.h unconditionally.

The include in tz.cpp was changed to only include the ios.h header
when compiling on apple platforms, as the documentation states that
only the four files date.h, tz.h, tz_private.h, and tz.cpp should be
required to use the time zone library.

Additionally, the ios.mm file was moved to src/ since it contains
C++ source code.

This is actually several separate C++11/C++14/C++17 libraries:

"date.h" is a header-only library which builds upon <chrono>. It adds some new duration types, and new time_point types. It also adds "field" types such as year_month_day which is a struct {year, month, day}. And it provides convenient means to convert between the "field" types and the time_point types.

"tz.h" / "tz.cpp" are a timezone library built on top of the "date.h" library. This timezone library is a complete parser of the IANA timezone database. It provides for an easy way to access all of the data in this database, using the types from "date.h" and <chrono>. The IANA database also includes data on leap seconds, and this library provides utilities to compute with that information as well.
"iso_week.h" is a header-only library built on top of the "date.h" library which implements the ISO week date calendar.
- Documentation: http://howardhinnant.github.io/date/iso_week.html
"julian.h" is a header-only library built on top of the "date.h" library which implements a proleptic Julian calendar which is fully interoperable with everything above.
- Documentation: http://howardhinnant.github.io/date/julian.html
"islamic.h" is a header-only library built on top of the "date.h" library which implements a proleptic Islamic calendar which is fully interoperable with everything above.
- Documentation: http://howardhinnant.github.io/date/islamic.html

"date.h" and "tz.h" are now being proposed for standardization:

Current proposal: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0355r4.html
Draft revision: http://howardhinnant.github.io/date/d0355r5.html
Status: The proposal was approved by LEWG and forwarded to LWG with the recommendation of targeting C++20 at the Albuquerque, NM meeting in Nov. 2017.
