Attach the specified timeZone to a plain datetime string and return a zoned ISO 8601 datetime string.
Combines plain datetime with timezone to create ZonedDateTime.
disambiguation controls DST gap/overlap resolution: “compatible” (default, matches Temporal’s default), “earlier”, “later”, or “reject” (throws, resulting in “”).
offset (“prefer” | “use” | “ignore” (default) | “reject”, per Temporal’s OffsetDisambiguationOptions) is accepted for API consistency with sibling zoned-construction functions (see startOfZoned, endOfZoned, etc.) but has no effect here: value is a plain datetime string with no UTC offset embedded, so there is never a stored offset for offset to prefer/use/ignore/reject against. disambiguation is the only option that affects this function’s output.
