ISO Datetime, minute precision (no timezone)

datetime.timestamp.iso_minutes

ISO 8601-like format with minute precision (T separator) and no timezone indicator (e.g. 2013-06-04T01:02). The minute-precision sibling of iso_seconds; common in exports that drop the seconds field.

Detection notes

Added 2026-07-11 (minute-precision timestamp family completion). Zoneless minute-precision sibling of iso_seconds, mirroring the seconds/millis/ micros ladder. Add-not-broaden: the zoned iso_8601 leaves keep their Z-required patterns. Recovered deterministically by datetime_format_refinement (the 244-dim model does not predict it).
