/**
 * This property editor allows the user to pick a date, datetime-local, or time.
 * It uses raw datetime strings back and forth, and therefore it has no knowledge
 * of timezones. It uses a regular HTML input element underneath, which supports the known
 * definitions of "date", "datetime-local", and "time".
 *
 * The underlying input element reports the value differently depending on the type configuration. Here
 * are some examples from the change event:
 *
 * date: 2024-05-03
 * datetime-local: 2024-05-03T10:44
 * time: 10:44
 *
 * These values are approximately similar to what Umbraco expects for the Umbraco.DateTime
 * data editor with one exception: the "T" character in "datetime-local". To be backwards compatible, we are
 * replacing the T character with a whitespace, which also happens to work just fine
 * with the "datetime-local" type.
