Calendar Month Linear Index Map proleptic year and 1–12 month to an exact linear month index with year zero; no day or timezone conversion.
Calendar Month Linear Index Inverse Invert a signed linear proleptic month index using floor division and astronomical year zero.
Calendar Month Span List List an inclusive bounded proleptic month span with explicit start and end; rejects backwards or oversized spans.
Calendar Quarter Month Offset Locate an ordinary calendar month within its calendar quarter; zero-based month offset, not a fiscal-quarter mapping.
Clock Components to Seconds Of Day Join validated ordinary civil clock components into seconds of day; leap-second 60 is not accepted.
Clock Forward Circular Gap Compute forward circular clock gap on a fixed 86,400-second day; equal clocks give zero.
Clock Offset with Day Carry Offset civil seconds of day and retain signed day carry; no time-zone transitions or date interpretation.
Clock Range Crosses Midnight Classify a forward civil clock range; equal endpoints mean empty, not an implicit full day.
Clock Shortest Circular Gap Compute shortest signed circular clock gap, half-day ties forward on a fixed 86,400-second day; equal clocks give zero.
Clock Value Window Membership Test half-open forward clock-window membership including overnight wrap; equal endpoints denote an empty window.
Clock Window Day Splitter Split each ordinary or overnight half-open civil clock window into same-day segments; no time-zone inference.
Clock Window Union Duration Merge overlapping civil clock windows after overnight splitting and count covered seconds once on the fixed day.
Duration Component Normalizer Normalize signed fixed-day duration components by floor division into a signed day count plus nonnegative subday components.
Duration Countdown State Classify an explicit countdown observation, retaining signed lateness; does not read a clock or schedule anything.
Seconds Of Day Splitter Split integer civil seconds of day into 24-hour clock components; no dates, zones or leap seconds.
Timestamp Epoch Offset Transform Translate integer timestamps between explicitly supplied epoch origins expressed in the same units; no calendar or leap-second conversion.
Timestamp Millisecond Component Join Join exact signed epoch second text and a 0–999 millisecond component without unsafe numeric conversion.
Timestamp Precision Loss Audit Audit exact integer timestamp precision loss when flooring to a positive unit quantum, retaining signed-era behavior.
Timestamp Second Millisecond Split Split an exact signed epoch millisecond integer into floor seconds and a nonnegative millisecond component.
