  "limitations": [
    "This is a deterministic arithmetic enumeration, not an empirical survey or a benchmark of third-party software.",
    "Excludes negative and subsecond inputs, durations beyond 24 hours, parsing, floating-point implementations, timezone, daylight-saving and payroll rounding policies.",
    "Zero changed four-place round trips is only a single-value nearest-second result on the stated corpus; it does not imply exact decimal values or exact sums."
  ],
  "additional": [
    "Four-decimal nearest-second preservation does not prove exact decimal representation, exact aggregation or behavior of third-party floating-point implementations.",
    "Minute chart covers 0..60 minutes; enumeration covers 0..86400 seconds. No payroll, billing, increment rounding or legal policy is implied.",
    "Decimal hours use ordinary 3600-second hours, not French Revolutionary decimal time."
