Revision as of 11:39, 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:
- +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 fordatetimevalues as precise as a specific day, e.g. YYYY-MM-DD. online casino spielen - -1 Hixie - "Without clear use cases, I don't intend to change the spec here." (ibid)
- +1 Tantek (per HTML5 Super Friends Technical Details: time element)
- +1 Andy Mabbett (Per use cases in VCARDDAV - see external links)
- ...
year month only
The time element should accept just a year and a month.
- ISO8601 syntax
- YYYY-MM
Opinions / discusion:

- +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 - see external links)
- Portable contacts allows this using a "0000" year value.
- ...
month day only
The time element should accept just a month and a day.
- ISO8601 syntax
- --MM-DD
- use case research
- http://microformats.org/wiki/birthday-examples#month_and_day_only
Opinions / discusion:
- +1 Tantek (per HTML5 Super Friends Technical Details: time element)
- +1 "radiz" implied support for --MM-DD with the use case question: "How to use <time> with a date in astrology?" in the article http://html5doctor.com/your-questions-answered-6/
- +1 Andy Mabbett (Per use cases discussed in VCARDDAV, e.g. birthdays, wedding anniversaries - see external links)
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 - 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 efforts" discussions - see external links)
- ...

- Extended Date Time Format efforts based at the USA's Library of Congress (Covers unspecific dates; date periods and non-Gregorian dates)

- vCard Format Specification draft-ietf-vcarddav-vcardrev-11 (latest draft as at July 2010)
- Section 4.3, date & time
- Section 5.7, CALSCALE (specifies Gregorian or other (e.g. Julian) calendar)
- ISO 8601 (Wikipedia article)
