Replace call to deprecated function format_date

HI maliknaik
Thanks for the patch. Are you responding to #3042677: Drupal 9 Deprecated Code Report for Scheduler? If so, can you add that as a parent issue and add a comment on that issue, otherwise someone else could duplicate the work.

Also can you remove the part of your patch which covers drupal::url as that is already dealt with in #3048600: Drupal::url() is deprecated, replace with \Drupal\Core\Url object

Thirdly, can you give a link to a change record on drupal.org so that we know exactly what was deprecated and in what release.

Thanks a lot
Jonathan

Thanks for the patch. All works fine.

However I can see that we are using Drupal::service('date.formatter') in six test files already. I think I will add this to the testBase first, then it is simpler to change the test files.

Interesting that the change record does not actually say that format_date() is deprecated. Are there any other doc pages you can find which say when the function will be deprecated?

Here's a patch which adds the dateFormatter service to SchedulerTestBase and uses that instead of creating $date_formatter in the actual test. I have also made the change in MetaInformation test. There are five other tests which would need this improvement, if you want to do those too?

Thanks. Committed.

Now that I've added the dateformatter object to SchedulerBrowserTestBase a separate issue can be opened to change the other four tests to use $this->dateFormatter

edit: Opened #3054372: Replace Drupal::service('date.formatter') with $this->dateFormatter in tests
