Sidereal vs Solar Time Converter implementation

Binding contract

This record describes what an executable surface must bind and validate. It does not claim that a public calculator, package, or production route is deployed.

Computation or source lookup only

Input and validation requirements

The stated multiplier produces overflow for a representable near-maximum JavaScript number unless the instrument rejects extreme inputs. The specification also leaves modulo-24-hour normalization and clock-time versus elapsed-duration conventions unspecified.

Required corrections

No binding erratum is attached to this unique-name record. Implementers must still preserve the declared units, domain, and failure behavior.

Inspectable interface fixture

The sample below is evidence for interface and validation tests, not a production implementation.

  "expected_outputs": {

    "sidereal_time": "01:00:09.85644"
  },
  "working": "1. Convert 1 hour to seconds: 1 × 3600 = 3600 s. 2. Apply the factor: 3600 × 1.0027379 = 3600 + (3600 × 0.0027379) = 3600 + 9.85644 = 3609.85644 s. 3. Convert back to h:m:s: 3609.85644 s = 1 h + 9.85644 s = 01:00:09.85644."
