cajeta.time.LocalDateTime — an immutable date-time without a time-zone: a LocalDate paired with a LocalTime (yyyy-MM-ddTHH:mm:ss.nnnnnnnnn), modeled on java.time.LocalDateTime. Stored canonically as int64 epochDay + int64 nanoOfDay; a pure stack value type. Arithmetic carries correctly between the time and date parts — adding hours can roll the date forward. Combine with a ZoneOffset to obtain an Instant or ZonedDateTime.

LocalDateTime dt = LocalDateTime.of(2026, 6, 8, 14, 30);
LocalDateTime later = dt.plusHours(12L);
int32 day = later.getDayOfMonth();   // 9 — carried into the next day
String text #= later.iso();           // "2026-06-09T02:30"
