Positions to evenly sampled datetime64/timedelta64 labels and back.

forward is exact int64 (positions are valid, so no overflow); reverse computes through python integers, so a label centuries away yields its true out-of-range position instead of wrapping — but returns float positions, as xarray’s transform contract asks, so its callers accept float rounding; the index’s own selection paths use _exact_positions instead.

Methods

Name	Description
equals	Two transforms are equal when they label every sample alike.
forward	Return the labels for the given positions.
reverse	Return the (float) positions for the given labels.
