/**
 * Persist {@link DateTime} as a string of three parts:
 * 
 * the {@code DateTime} transformed into UTC time, formatted as such: {@code yyyy-MM-dd'T'HH:mm:ss.SSS}
 * the underscore symbol (_)
 * the id of the {@code DateTime}'s original time zone (for example Europe/London or UTC)
 * 
 * This user-type was created to workaround Hibernate's HHH-5574
 * bug by storing the complete {@code DateTime} data, including the specific time zone, not just the offset (ala ISO 8601), in
 * one single, sortable field.
