' property) would be most useful when combined with a new HTML tag used to identify dates, such as this theoretical example:speak-date <p>The campaign started on <date value="1874-oct-21"> the twenty-first of that month</date> and finished <date value="1874-oct-28">a week later</date>
Some have advocated the creation of a <date> tag that would display dates according the locale of the user agent. This is subject to the same practical issues as described for dynamic date generation with the Japanese example. The appropriate format is generally a function of the linguistic context of a page, rather than the user's platform.
My first instinct was to try the <object> tag, since it has a nice mechanism for providing data within its 'data' attribute, and fallback plain text inside the element itself, e.g. (simplified for sake of discussion):
<object data="20050125">January 25</object>This worked great in typical modern browsers, except for one: Safari (v1.2.1). Unfortunately, to put it mildly, Safari's <object> support sucks. It doesn't handle <object> fallbacks, it doesn't know when not to handle <object> mime types that it doesn't support, it doesn't support display:inline on <object>, and it doesn't do proper intrinsic sizing of <object> replaced elements. These are all trivial to reproduce bugs.
Humans don't think of dates and times in terms of fully qualified year, month, date, hour, minute, second, time-zone values. Humans think of dates and times in terms of only that which is necessary. The day, or the day and the month, or perhaps just the hour. What do all these have in common? They are all abbreviations for a fully qualified date and time.
Lucky for us, XHTML has an element for abbreviations: <abbr>.
Thus, the ISO8601 date 20050125 should be marked up as:
<abbr title="20050125">January 25th</abbr>

を定義した。<t> (or an equivalent) has been widely requested, especially in the microformats and CSS communities. Several microformats have need for encoding specific times and/or dates, and are currently (ab?)using <abbr> for this purpose. The CSS community has requested a <date> or <time> element because they want to restyle dates and times according to locale. The blogging and content publishing communities have also raised the need for a way to unambiguously mark up what part of their document is a date and/or time, though in their case (as with microformats) they need a way to then mark each date/time element as being a particular semantic (publishing date, birth date, calendar event time etc).
Also, the aforementioned research indicated that there are substantial amounts of content on the Web that uses invented elements, IDs, and class attributes to mark up dates and times. For example, I found about the same number of pages with the obscure ID "updatedtime" as I did pages with a <button> element; "date" was the 14th most frequently seen class name.
