Imagine I have a following json schema:

"period": {
           "type": "object",
           "properties": {
           "start": {
              "description": "Unixtime",
              "type": "number",
              "minimum": 0
            },
           "end": {
              "description": "Unixtime",
              "type": "number",
              "minimum": 0
            }
          },
          "required": [
           "start",
           "end"
          ]
        }

Is there a way to ensure that start time is always <= end time with help of schema itself?
