False precision

A timestamp stored to nanoseconds from a clock accurate only to ±1 second implies precision the source never had. The extra digits are noise that can flip a near-boundary slot assignment.

Class

Case to account for

Affects

1 conversion

Detection

Stored precision (digits) exceeds the clock's stated accuracy.

Mitigation

Round to the clock's real resolution; carry accuracy so downstream code does not over-trust the digits.

Affected conversions

Timestamp + zonehour-of-week slot
