Mail Routing Hop Delay

Measure one recorded administrative mail-routing hop on a shared timestamp scale.

Description

Calculate a supplied mail-routing hop delay.

Administrative records distinguish delegated authority, sign-off assertions, conditional fields, counter-minutes and date boundaries. A half-open delegation period excludes its final date, and staffed-counter time can sum simultaneous counters. Local flags and fees do not authenticate an approval or establish lawful authority or adequate service.

Calculate a supplied mail-routing hop delay.

When to use this tool

Use Mail Routing Hop Delay when you already have receivedTimestampSeconds, forwardedTimestampSeconds and need to calculate a supplied mail-routing hop delay.

How to use the tool and how it works

  1. Enter receivedTimestampSeconds, forwardedTimestampSeconds. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read hopDelaySeconds. Use the output convention below.

Require forwardedTimestampSeconds>=receivedTimestampSeconds; return forwarded-received.1

Input fieldMeaning and unitsAccepted input

{
  "input": {
    "receivedTimestampSeconds": 100,
    "forwardedTimestampSeconds": 145
  },
  "output": {
    "hopDelaySeconds": 45
  }
}

Limitations and assumptions

  • Zero delay is allowed. No message, clock synchronization, delivery, route or adequate service performance is 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

Check controlled policies, original case records, verified roles and account definitions. Apply complete administrative and legal processes when local routing delays, document counts or supplied approval comparisons cannot determine a valid action.
