Add functionality for all-day events

I close it as 8.x branch is not supported anymore.

Which means the new feature quested won't be consider anymore.

Re-opened because the patch in #17 was re-rolled against the 5.x branch and the feature request is still valid (5.x doesn't support all-day functionality for a single day).

Is this feature request meant to address the undesired display of a time on All Day events? If the event is All Day, I don't want the time (12:00AM) to appear on the event in the calendar.

While the original issue summary does not mention using smart_date for all day functionality, smart_date is mentioned quite a few times in the comments. I'm reporting that smart_date 4.0.2 is working out of the box with fullcalendar_view 5.1.12 with all day functionality, without requiring any patches.

Perhaps what some are missing is that the field type has to be "Smart date range" and not, the core "Date range" with Smart date widget.

Download and enable the Smart Date Calendar Kit → on a new Drupal install and look at how it's configured.

This patch causes warnings if the end date is not set.

Here is a new patch. Adds some checks for empty values and addressed some phpcs issues.

I updated the patch that @geekygnr left in comment #25 to be compatible with the latest version 5.1.13

@LeonelEnriquez98 The patched worked for the most part but its posting two days. So I post an event for 1 day 11/20 but when viewing it's showing all day for 11/19 and all day 11/20 for the same event. I just added the start date only and also did the say day for Start and End date and still the same issue.

@ferminaguilar I could reproduce that error. It was related to the timestamp variable. So here I leave the new patch.

@ferminaguilar @LeonelEnriquez98 I still had the same issue with all-day events starting on the day before they should after applying patch #28. I believe the issue is because when finding the start date, it applies the difference from UTC to a date which has already had the difference applied to it. So it applies the timezone difference twice. Here's a new patch.

@jennine Your patch seems to be working fine. Thanks!

Patch #30 fixed the starting a day early for me... but now they are running a day over. I assume that's because my events are coming in with a start date of 00:00:00 day 1 to 00:00:00 day 2. Trying to figure out if I need to adjust the patch for my situation or if I have something configured wrong.
