devel/cctz 2.2_3 DragonFly

CCTZ contains two libraries that cooperate with <chrono> to give C++ programmers all the necessary tools for computing with dates, times, and time zones in a simple and correct manner. The libraries in CCTZ are:

_ The Civil-Time Library - This is a header-only library that supports computing with human-scale time, such as dates (which are represented by the cctz::civil_day class). This library is declared in civil_time.h.

_ The Time-Zone Library - This library uses the IANA time zone database that is installed on the system to convert between _absolute time_ and _civil time_. This library is declared in time_zone.h.
