Description
Calculate supplied sensor-minus-reference timestamp offset.
Farm data records preserve task, device, field-boundary, source-permission and unit identifiers. A supplied area-unit label is not a conversion, while a sensor/reference clock gap is not synchronization. Version and permission references record assertions rather than validating a complete device or agricultural data standard.
Calculate supplied sensor-minus-reference timestamp offset.
When to use this tool
Use Farm Sensor Timestamp Offset when you already have referenceSeconds, sensorSeconds and need to calculate supplied sensor-minus-reference timestamp offset.
How to use the tool and how it works
- Enter referenceSeconds, sensorSeconds. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read signedGap. Use the output convention below.
Return sensorSeconds-referenceSeconds, preserving signs.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| referenceSeconds | Reference Seconds | Required. Finite number. |
| sensorSeconds | Sensor Seconds | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| signedGap | Signed Gap | Required. Finite number. |

"input": {
"referenceSeconds": 12,
"sensorSeconds": 17
},
"output": {
"signedGap": 5
}
}Limitations and assumptions
- This estimates nothing beyond supplied clocks; applying this offset for correction would subtract it from sensor time. No synchronization, drift or event alignment is verified.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Check actual device, task, boundary and source records with the full format and controlled vocabulary. Verify calibration, time alignment and permissions before relying on local keys or labels in an operational workflow.
