implements DXNValueInterface

DXN `local-datetime` (`@local-datetime "2026-10-20T14:30:00"`) -- a date and a time on the wall clock, with no offset, so no instant (DXN.md §1.3; Jan, 2026-10-20). Held as `.dxnb` holds it: nanoseconds since 1970-01-01T00:00:00 on the wall clock.

DXNValueInterface

Implemented by every `DXN*` wrapper class -- the PHP analog of the `dxnType` string tag used for kind dispatch in the JS port, and of `Dextrin.Value`'s closed type union in the Elixir original. Native PHP values (`null`, `bool`, `int`, `float`, `string`, and `array` for `map`/`array`) never implement this; {@see Equality::kindOf()} handles those directly.

Constants

DXN_TYPE  : mixed = 'local-datetime'

Properties

$localNanoseconds  : int

Methods

__construct()  : mixed

compareTo()  : int

A total order against any other DXN value, not just another instance of this class -- backs {@see DXNSortedSet}. Cross-kind ordering is implementation-defined per DXN.md; within a kind, uses the kind's own natural order where one exists, or a deterministic structural fallback where it doesn't.

dxnType()  : string

The DXN type name this value represents, e.g. "symbol", "uuid".

equals()  : bool

Structural equality, recursing into nested DXN values as needed.

fromDateTimeImmutable()  : self

`$date`'s wall clock, its zone dropped.

toDateTimeImmutable()  : DateTimeImmutable

This wall-clock time in `$zone` (UTC when none is given), to the microsecond -- a local date-time names no zone of its own, so the caller picks one.
