Proper datetime attribute for <time>

问题

While Schema.org writes

Here is an example: <time itemprop="openingHours" datetime="Tu,Th 16:00-20:00">Tuesdays and Thursdays 4-8pm</time>.

on the HTML5 validator I get this error:

Bad value Mo, Tu, We, Th, Fr 09:00-16:00 for attribute datetime on element time: The literal did not satisfy the time-datetime format.

…" datetime="Mo, Tu, We, Th, Fr 09:00-16:00">every work day 9am to 16pm </time></li>

I really want to communicate the opening hours (and days) in Microdata, but it seems this is in conflict with HTML5.

Is there a format that is good for both or I should keep it for the bots and care not about valid HTML in this case?

回答1:

I would suggest to keep what you have and not worry about the HTML validator which is only a guide at any rate.

回答2:

Don’t use the time element.

It’s an error with Schema.org’s documentation. I reported this issue in the Schema.org tracker and it will likely be fixed in the next release.

Possible alternatives:

• data element:

  <data itemprop="openingHours" value="Tu,Th 16:00-20:00">Tuesdays and Thursdays 4-8pm</data>
  

• meta element (which can be used in the body):

  <meta itemprop="openingHours" content="Tu,Th 16:00-20:00"> Tuesdays and Thursdays 4-8pm
