Appearance

formatDateTime ​

formatDateTime(value): string

Defined in: js-xbbg/src/index.ts (declaration: index.d.ts:1004)

Format a datetime-like value to RFC 3339 (ISO 8601 with optional offset).

Naive ISO strings without a tz suffix are returned as-is so the Rust engine can apply the caller's request_tz. Anything else (Date, epoch ms, Luxon DateTime, or ISO with explicit tz) is converted to a tz-bearing ISO string.

Parameters ​

value ​

DateLike

Returns ​

string
