Description
Return waveform event time after a supplied origin/clock shift.
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 waveform event time after a supplied origin/clock shift.
When to use this tool
Use Waveform Event Time Offset when checking the stated benign record, simulation, timing or bench-measurement convention.
How to use the tool and how it works
- Enter eventTime, recordingOrigin, suppliedClockShift. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read relativeTime. Use the output convention below.
Return waveform event time after a supplied origin/clock shift. relativeTime = eventTime+suppliedClockShift-recordingOrigin.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| eventTime | Event Time | Required. Finite number. |
| recordingOrigin | Recording Origin | Required. Finite number. |
| suppliedClockShift | Signed shift added after subtracting recordingOrigin. | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| relativeTime | Relative Time | Required. Finite number. |

}Limitations and assumptions
- The shift is added under this convention; no physiological event detection, clinical timing or actual clock synchronization is established.
- 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.
