Before this rev., the 'fieldChanged' event was triggered each time the user selected a value (a day, an hour, a minute or a second) in the datepicker. This means that if there was an onchange on the field, a lot of RPCs could have been done when a user set a datetime. In addition, in a list view with multi edition, the user was asked to save the changes at each step of the datetime selection, making the feature unusable. Task 2068280
