This field allows to associate calendar items with tracker items. Added in Tiki18

The options are:

The tracker interface displays only the Start date but it is possible to create a recurring event to link several dates to a single items, for example Museum Open 10:00 to 17:00 Monday, Tuesday, Thursday and Friday and have the objects retrieved (filtered) through the unified-index.

For example you can create an event “Summer Seminar” that is a recurrent event from Monday to Thursday from the 2/09/2022 to 6/09/2022.
It will create several objects (days) with a common recurrence id.
In the plugin list you will be able to filter calendar items using the recurrence id.

Change tracker date fields with date-only storage to use 12am GMT timestamp instead of user's timezone 12am time, add a migration to fix existing timestamps for tracker date-only fields to use 12am GMT, fix conversion to gmdate in the search index.

The former preference "Admin home > Calendar > Jscalendar" seems to have no effect on the tracker field "Date and Time (Date Picker)". In some previous Tiki versions, the Js Calendar setting added a visual selector of dates based on javascript (earlier than the Jquery date picker widget).

Date Only is currently only available in tikiwiki 1.9, the other two are available in tikiwik>=1.9
The options on Date & Time and Jscalendar types are only available in tikiwiki>= 1.10

Here is an example of the plugin tracker on a tracker using different comfiguration of these fields

In this example you see the popup of the jscalendar field that has been opened. Note that this image does not depict the Date Only field.

The option is :

It the date_time is date, the user will be ask to enter only a date not a time.It the date can be blank, the user can not fill the field.
