Add support for importing Time fields

[jamesmacwhite]

Description

This adds initial support for Feed Me to properly handle Craft time fields. Currently time fields are only possible to be imported when times are written as strings. This update parses time values through the DateHelper to ensure they are valid. Using the existing DateHelper, the parseTimeString method is used to parse mapped values.

In addition, the default value on the mapping uses a Craft time field, rather than a plain text field

The following test data was used as part of testing:

{
  "content": [{
    "title": "Example entry title 1",
    "startTime": "13:00",
    "endTime": "15:00"
  }, {
    "title": "Example entry title 2",
    "startTime": "01-01-1900 16:00",
    "endTime": "01-01-1900 18:00"
  }]
}

This is the initial starting point to ensure time fields can be used in Feed Me, currently there is no proper handling of this field type leading to issues with importing.

Thanks for this, @jamesmacwhite! I’m closing this in favour of #1593.

I cherry-picked your commit into that new PR so that it can target v5 (for Craft 4). It’ll also be merged into v6 (for Craft 5) if approved. I added support for formats (just like date fields have) so we don’t get into trouble when the date is provided and uses a different format.

Hi @i-just. Thanks for picking this up and improving on it! Great to have time field support hopefully in the next release!
