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.
"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.
"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.
Slightly modified versions of "date.h"
and "tz.h"
were voted into the C++20 working draft at the Jacksonville FL meeting on 2018-03-17:
You will need CMake and a recent C++ compiler. Here follows a guide of how to build and test using the CMake Makefile generator.
mkdir build cd build cmake ../ cmake --build . --target testit # Consider '-- -j4' for multithreading
If you would like your project (or product) on this list, just let me know.
