* This is a synonym for static_cast<precision>(*this). * This variation can be easier to spell when the precision is not conveniently available.
This is actually two separate C++11/C++14 libraries:
-
"date.h"
is a header-only library which builds upon<chrono>
. It adds some newduration
types, and newtime_point
types. It also adds "field" types such asyear_month_day
which is a struct{year, month, day}
. And it provides convenient means to convert between the "field" types and thetime_point
types. See http://howardhinnant.github.io/date_v2.html for more details. -
The other files 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. See http://howardhinnant.github.io/tz.html for more details.
