Description
Return markerTime minus referenceTime minus suppliedClockOffset as offset.
Research timing records need a common clock origin, time unit and observation boundary. A corrected interval or censored duration describes the supplied recording model; it does not by itself measure physiological transit or establish a diagnosis.
Return markerTime minus referenceTime minus suppliedClockOffset as offset.
When to use this tool
Use Research Transit Marker Time Offset when you need a research timing, frame or clock-reference calculation.
How to use the tool and how it works
- Enter markerTime, referenceTime, suppliedClockOffset. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read offset. Use the output convention below.

| markerTime | Marker Time | Required. Finite number. |
| referenceTime | Reference Time | Required. Finite number. |
| suppliedClockOffset | Supplied Clock Offset | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| offset | Signed displacement or phase under the convention above. | Required. Finite number. |

}Limitations and assumptions
- All times share units and origin; signed offsets are retained. This is research clock arithmetic, not a physiological transit assessment.
- 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
Use original timestamps and the study protocol to resolve timing conventions. Physiological interpretation requires the appropriate clinical or research assessment, including observation and calibration uncertainty.
