Description
Calculate incident timestamp precision width from explicit caller-supplied inputs.
Security records often depend on explicit counts, clock origins, status flags, and provenance dates. Checking their internal arithmetic can reveal a bookkeeping gap while leaving the underlying evidence and operational decisions for separate review.
Calculate incident timestamp precision width from explicit caller-supplied inputs.
When to use this tool
Use it for incident timestamp precision width when the required inputs and conventions are already available.
How to use the tool and how it works
- Enter earliest, latest. Use the stated units and boundary conventions.
- Run the calculation. Correct any input error before interpreting a result.
- Read width, midpoint. Inspect any known, defined, inclusion, or boundary flags before interpreting numeric values.
Require latest no earlier than earliest and return their interval width and overflow-resistant midpoint earliest/2+latest/2.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| earliest | Earliest | Required. Finite number. |
| latest | Latest | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| width | Width | Required. Finite number. |
| midpoint | Midpoint | Required. Finite number. |

}Limitations and assumptions
- These are supplied timestamp bounds in a common unit and clock, not a probability distribution or verified incident timing. Midpoint does not make an uncertain timestamp exact.
- The field tables describe structural bounds; the mechanics also state cross-field requirements. Malformed input shapes, disallowed keys, and invalid domains cause input errors. Results must remain finite and within the declared output contract. A successful false flag or zero placeholder is distinct from an error.
- Numeric arithmetic uses binary floating point. Exact comparisons have no hidden tolerance or decimal rounding; negative zero is exported as zero. Decimal-text integer operations retain the exactness specifically stated above.
Alternative or Complementary methods
For incident timestamp precision width, check the source records and the supplied rule before comparing the result with another method. Use a separate evidence or method review when arithmetic consistency alone cannot establish the required conclusion.
