Description
Return the absolute epoch-second difference and possibleDuplicate for an inclusive comparison with tolerance.
Personal health and activity records use supplied observations, labels, and time intervals. A formatter or simple summary can organize those records without assessing health, diagnosing a condition, or recommending treatment.
Return the absolute epoch-second difference and possibleDuplicate for an inclusive comparison with tolerance.
When to use this tool
Use Health Log Duplicate Reading Time Gap when you need a bounded personal-record calculation with explicit units and date conventions.
How to use the tool and how it works
- Enter firstEpochSeconds, secondEpochSeconds, toleranceSeconds. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read gapSeconds, possibleDuplicate. Inspect possibleDuplicate before interpreting the associated values.
Require nonnegative toleranceSeconds. Return the absolute epoch-second difference and possibleDuplicate for an inclusive comparison with tolerance.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| firstEpochSeconds | First Epoch Seconds | Required. Safe integer. |
| secondEpochSeconds | Second Epoch Seconds | Required. Safe integer. |
| toleranceSeconds | Tolerance Seconds | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| gapSeconds | Gap Seconds | Required. Finite number. |
| possibleDuplicate | Possible Duplicate | Required. Boolean. |

}Limitations and assumptions
- Timestamps alone cannot establish identical measurements or authorize deletion; values, source device, timezone provenance, and record identity are not inspected.
- 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
Review the original observations and consult an appropriate health professional for clinical interpretation or care decisions.
