Overview

This class is a less strict extension of ActiveSupport::Duration::ISO8601Parser. In addition to full ISO8601 durations, it can parse unprefixed ISO8601 time components (e.g. ‘1H’). It is also case-insensitive. For example, this class considers the values “1H”, “1h” and “PT1H” to be valid and equivalent.
