normalized
Normalizes the date property to a system-compatible temporal representation.
Processes the underlying date or date-time of the DateProperty to ensure compatibility with content providers by converting ical4j-specific temporal types to system-known types:
Converts OffsetDateTime to Instant (UTC timestamp).
Converts ZonedDateTime with ical4j-based timezones to ZonedDateTime with system-known ZoneId.
Leaves Instant, LocalDate, and other temporal types unchanged.
Return
A normalized Temporal object: - Instant for UTC date-times (originally OffsetDateTime). - ZonedDateTime with system-known ZoneId for date-times with TZID. - Original Temporal type for other cases (Instant, LocalDate, etc.).
