RFC 3339 (Space Separator)

datetime.timestamp.rfc_3339

Internet datetime format, a profile of ISO 8601 that allows a space separator between date and time (RFC 3339 §5.6). Used in Atom feeds, JSON APIs, and modern web services. Distinguished from iso_8601_offset by the space separator: RFC 3339 uses space, ISO 8601 requires T. Disambiguation: Tier 2 timestamp model detects T vs space.
