Revision as of 11:44, 13 July 2010

Research, data, use cases, issues, and enhancements related to the HTML5 time element.

year only

The time element should accept just a year.

ISO8601 syntax
YYYY
use case research
http://microformats.org/wiki/birthday-examples#year_only

Opinions / discusion:

year month only

The time element should accept just a year and a month.

ISO8601 syntax
YYYY-MM

Opinions / discusion:

  • +1 Faruk (per Bug 7145 - Valid date strings should accept ambiguous inputs, like "2009" or "2007-01") One example is the very common archive view found on most blogs, which contain distinct links or headers for each year, each month per year, and often each date within a chosen or highlighted month. Currently, the <time> element only allows for datetime values as precise as a specific day, e.g. YYYY-MM-DD.
  • -1 Hixie - "Without clear use cases, I don't intend to change the spec here." (ibid)
  • +1 Tantek I think the blog archives use case (where blogs often link to their archives by a specific month and year) is sufficient to justify adding this capability to the time element. Content hosting sites like Flickr also list archives by specific year/month, e.g. see http://www.flickr.com/photos/tantek/archives/
  • +1 Andy Mabbett (Per use cases in VCARDDAV & EDTF - see external links)
  • ...

month day only

The time element should accept just a month and a day.

ISO8601 syntax
--MM-DD
use case research

Opinions / discusion:

Calendar

The time element should accept a calendar scale (default is GREGORIAN) per the emergent vCard 4 specification, to facilitate the mark-up of non-Gregorian (e.g. Julian) dates.

Opinions / discussion:

  • +1 Andy Mabbett (Per use cases in VCARDDAV & EDTF - see external links)
  • ...

Fuzzy dates

The time element should accept fuzzy (uncertain, approximate) dates and eras.

Opinions / discussion:

  • +1 Andy Mabbett (Per use cases in "Extended Date Time Format" proposals - see external links)
  • ...
