This package provides functionality for working with time and strings based on the ISO 8601 standard i.e. 2016-03-31T12:13:14.22-04:00

It is a "pure" Elm package – no Native bindings to Javascript's Date are used. This does have a performance cost. This package is about 10x slower than the core Date library. But there are advantages:

• Does not cast the time in the local timezone
• Preserves the timezone offset values
• Detects invalid dates
• Provides a record with easy access to the time's components
• Specific error messages

TODO

• Get the day of the week
• Support for simple math (Add, Subtract and Durations)
• Support the ISO 8601 range syntax
