Description
Return elapsed log time only when origin is known.
Anesthesia-related research and training records require explicit clocks, missingness flags, exclusions and measurement references. These tools reconcile benign records, simulations or bench data; an acceptable local overlap or composition sum does not establish clinical adequacy or safe patient care. Censored observations provide bounds rather than observed event times.
Return elapsed log time only when origin is known.
When to use this tool
Use Anesthesia Log Clock Origin Flag when checking the stated benign record, simulation, timing or bench-measurement convention.
How to use the tool and how it works
- Enter localTime, originTime, originKnown, suppliedOffset. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read elapsedDefined, elapsed. Inspect elapsedDefined before interpreting the associated values.
Return elapsed log time only when origin is known. elapsedDefined mirrors originKnown; elapsed = localTime-originTime+suppliedOffset when known, otherwise zero.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| localTime | Local Time | Required. Finite number. |
| originTime | Origin Time | Required. Finite number. |
| originKnown | Origin Known | Required. Boolean. |
| suppliedOffset | Supplied Offset | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| elapsedDefined | Elapsed Defined | Required. Boolean. |
| elapsed | Elapsed | Required. Finite number. |

}Limitations and assumptions
- Zero with elapsedDefined false is a placeholder; actual clock origins and clinical event history are not 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
Use verified source records and appropriate complete analysis for research or quality review; seek qualified medical and engineering assessment for actual clinical care or equipment decisions.
