Description
Return repliedAt-requestedAt and window minus that elapsed value.
Extension-service time budgets distinguish contact, travel, closed cases, credited pauses and source-validity periods. Allocated person-time differs from elapsed time, while half-open source periods differ from closed deadline checks. A supplied deadline or pause is not automatically an official service requirement.
Return repliedAt-requestedAt and window minus that elapsed value.
When to use this tool
Use Advisory Reply Window Gap when checking the stated contact/travel, response or source-period convention.
How to use the tool and how it works
- Enter requestedAt, repliedAt, suppliedWindow. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read elapsed, slack. Use the output convention below.
Require a nonnegative supplied response window. Return repliedAt-requestedAt and window minus that elapsed value.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| requestedAt | Requested At | Required. Finite number. |
| repliedAt | Replied At | Required. Finite number. |
| suppliedWindow | Supplied Window | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| elapsed | Elapsed | Required. Finite number. |
| slack | Slack | Required. Finite number. |

}Limitations and assumptions
- Negative elapsed time is retained; clock consistency, reply quality and real service requirements 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 clock, journey and source records with the governing service and reimbursement policies for actual performance or payment decisions.
