r-clock
Date-Time Types and Tools. Provides a comprehensive library for date-
time manipulations using a new family of orthogonal date-time classes
(durations, time points, zoned-times, and calendars) that partition
responsibilities so that the complexities of time zones are only
considered when they are really needed. Capabilities include: date-time
parsing, formatting, arithmetic, extraction and updating of components,
and rounding.
