* When year < 0, -year > 0 (always). * These are the minimal limits C places on short. * Reserving -32768 is useful in the implementation.
This is actually several separate C++11/C++14 libraries:
-
"date.h"is a header-only library which builds upon<chrono>. It adds some newdurationtypes, and newtime_pointtypes. It also adds "field" types such asyear_month_daywhich is a struct{year, month, day}. And it provides convenient means to convert between the "field" types and thetime_pointtypes. -
"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/p0355r3.html
-
Revision 4 draft: http://howardhinnant.github.io/date/d0355r4.html
