Description
A display-duration timer compares elapsed civil days with a separately established protocol duration.
A display-duration timer compares elapsed civil days with a separately established protocol duration.1
Negative remaining days show how long that supplied allowance has been exceeded.
When to use Display Duration Etiquette Timer
Use this tool to apply the stated display duration etiquette timer operation with an explicit input and unit basis.
How to use Display Duration Etiquette Timer and how it works
- Establish the measurement basis and units described above.
- Enter actualDisplayStartUtcIsoDate, actualReviewUtcIsoDate, callerIndependentlyApplicableDisplayDurationDays and run the tool.
- Read result.elapsedDisplayDays, result.signedRemainingCallerDays, result.callerDurationExceeded using the output meanings below.
- If input is rejected, correct the stated type, range, ordering or alignment issue and rerun; review successful results under the declared convention.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualDisplayStartUtcIsoDate | Display start utc iso date, on the basis specified in the algorithm. | string | required; further conditions in the algorithm |
| actualReviewUtcIsoDate | Review utc iso date, on the basis specified in the algorithm. | string | required; further conditions in the algorithm |
| callerIndependentlyApplicableDisplayDurationDays | Independently applicable display duration days, on the basis specified in the algorithm. | number | required; finite; integer from 0 to 1000000; further conditions in the algorithm |
Validate ordered real UTC YYYY-MM-DD dates and integer duration 0–1,000,000. Return elapsed days, duration minus elapsed, and an exceeded flag using strict greater-than.
remaining = allowed − elapsed; exceeded = elapsed > allowed Apply the declared units, ordering and branch conditions.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the declared output fields. | object |
| result.elapsedDisplayDays | Elapsed whole UTC civil days. | number |
| result.signedRemainingCallerDays | Allowed days minus elapsed days; negative values mean overdue. | number |
| result.callerDurationExceeded | True only after the allowed duration has been exceeded, not at equality. | boolean |

}Limitations and assumptions
The output applies the declared operation to the values you supply. Establish the measurement basis, units, coefficients and any caller-selected rules before interpreting it. The tool does not independently collect or verify observations or decide whether a model or reference applies.
Supply explicit required fields with the documented types and dense aligned arrays. Unknown fields, wrong types and nonfinite numbers are rejected. Branch-specific constraints are explained above. A successful false boolean, negative signed difference, empty slice or unresolved tie is distinct from an input error. Very large inputs or outputs may be rejected by shared resource limits.
Alternative or Complementary methods
For a related operation, use Flag Retirement Condition Rater. Flag retirement depends on the observed condition and the applicable organization's practice.
For a related operation, use Indoor Parade Fringe Suitability Checker. Fringe suitability depends on the flag's use, governing protocol and organization.
