Overview

Shared base for the Bolt temporal value types: Duration, LocalDateTime, LocalTime, OffsetTime. Each subclass declares its significant_fields and gets <=>, ==, eql?, hash derived from them automatically. Comparable mixed in here gives <, >, between?, clamp etc. for free.

Direct Known Subclasses

Duration, LocalDateTime, LocalTime, OffsetTime
