The measured difference between a device clock and a reference time source. Records what was compared, the offset value, and when the comparison was made.
Instances of solveit-observable:ClockOffsetMeasurement can have the following properties:
| PROPERTY | TYPE | DESCRIPTION | RANGE |
|---|---|---|---|
| From class solveit-observable:ClockOffsetMeasurement | |||
| solveit-observable:clockOffsetKnownAt | owl:DatatypeProperty | The specific point in time when this clock offset was determined. | xsd:dateTime |
| solveit-observable:clockOffsetValue | owl:DatatypeProperty | The clock offset value in seconds. Positive values indicate the clock is ahead, negative values indicate it is behind. | xsd:decimal |
| solveit-observable:referenceTimeSource | owl:DatatypeProperty | The reference time source used for comparison (e.g., NTP server, GPS time, examiner's calibrated watch). | xsd:string |
