HTML5 datetime value test - fraction safe

This test is based on HTML5 datetime value examples listed in HTML Living Standard 4.6.11 The time element description*. An HTML5 user agent should parse all of the following (time elements content and datetime attirbute values) as valid datetime values.

*Except fractional parts of second are trimed to 3 digits (from original 5 digits), so that those conform to the definition "One, two, or three digits" in the spec.

A valid local date and time string

A valid time-zone offset string
