Time and Date
Support for international date/time calculations was very limited in the
early years of Java. In this vacuum the Joda-Time
by Stephen Colebourne became the de-facto standard for advanced date/time logic
which finally became part of the JDK
(Java 8, JEP 150).
The package java.time
provides a solid API for date/time calculations and local representations of
time stamps in different calendar systems.
