Custom Attribute For Fatigue driving

Hi,
I want to generate an alarm for Fatigue Driving when a vehicle's ignition remains continuously on for a specific duration, such as 4 hours. Please let me know if this is possible through this attribute.

Through ignition

{
  "type": "attribute",
  "attributes": [
    {
      "key": "Ignition",
      "type": "Boolean"
    }
  ],
  "operator": "&&",
  "conditions": [
    {
      "type": "time",
      "key": "Moving_Duration",
      "comparison": ">",
      "value": "4:00:00"
    },
    {
      "type": "attribute",
      "key": "Ignition",
      "type": "Boolean",
      "value": true
    }
  ],
  "ifTrue": "Fatigue driving",
  "ifFalse": "null"
}

Just Through Moving duration

{
  "type": "attribute",
  "attributes": [
    {
      "key": "Continuous_Moving_Duration",
      "type": "Time"
    }
  ],
  "operator": ">",
  "value": "4:00:00",
  "ifTrue": "Fatigue driving",
  "ifFalse": "null"
}

It's not possible through computed attributes.
