Date API

How do I update the DATE and DATE API modules on my site from 7.x-2.10 to 7.x-2.11-beta2?

I tried to update using the command: composer require 'drupal/date:^2.11'

But I received the errors:
- drupal/date_api 2.10.0 requires drupal/date 2.10.0 -> satisfiable by drupal/date[2.10.0] but these conflict with your requirements or minimum-stability.
- Installation request for drupal/date_api (locked at 2.10.0) -> satisfiable by drupal/date_api[2.10.0].

hey there,

I'm studying Views in order to build a module that will use date parts as contextual filters.

with that in mind, I need to know how can I pull a list of date fields (both core and custom date fields) that I can manipulate in simple ways (at first YYYY, MM, DD, but later on maybe weeks within a month or suggestions from users).

is there any tutorial on that? paid solutions (video courses, books etc.) also welcome.

thanks in advance,
Luciano

We want to use HTML5 date fields where we can, but there are going to be a lot of issues.

There are a whole list of possible fields to use: date, datetime, datetime_local, week, month, etc. (see http://www.w3.org/TR/html5/states-of-the-type-attribute.html#date-and-ti...)

If you go to http://html5test.com/ and test various browser support, you can see that none of the HTML5 date fields work reliably across desktop browsers. In fact I only found one desktop browser that supported any HTML5 date field -- Chrome supports the 'date' type but nothing else.

After talking with Karen at the Midwest Developer Conference I am very excited to help out working on bringing the date module functionality into Drupal 8. There is a lot of work to do in order for that to happen. We need to:

• Separate the code that can become a Component from the code that needs to be Drupal specific
• Separate the code that needs to be a library (PSR-0) and the stuff that needs to be in the module directory
• Separate the code that should be put into core from the core that will live on as a community-driven module.

We're hoping to do some sprints around a potential effort to get parts of Date in core at the DrupalCamp New York July 19-23 (http://www.nyccamp.org/) and Midwest Developer Summit, July 26-28 (http://midwest-developer-summit.com/).

The sprints will involve discussions about which parts should go into core and a strategy for getting them there.

Please join us if you can!!

There is lots of concern about the performance of dates. There are actually two parts to this:

• the time it takes to retrieve date values stored in one method or another, a database issue.
• how much time it takes to massage the raw data into the desired format for display, a PHP issue.

The second one is the real bottleneck when working with dates, and is unrelated to the storage method being used. This page is to discuss the first topic, the part of the performance that is related to the storage method that is used.
