Bug in @filter() for day indexed edge

P.P.S. It’s not the type system either, from what I can see.

{
 	q(func:has(hours.tracked)) @filter(gt(hours.tracked,2019-01-01)){
      hours.tracked
  }
}

Gives:

{
  "data": {
    "q": [
      {
        "hours.tracked": "2019-10-17T00:00:00Z"
      },
      {
        "hours.tracked": "2019-10-24T00:00:00Z"
      },

Whereas:

{
 	q(func:has(hours.tracked)) @filter(gt(hours.tracked,2020-01-01)){
      hours.tracked
  }
}

Gives:

{
  "data": {
    "q": []
  },
  "extensions": {
    "server_latency": {
      "parsing_ns": 137500,
      "processing_ns": 28087400,
      "encoding_ns": 15600,
      "assign_timestamp_ns": 2130300,
      "total_ns": 30931800
    },
    "txn": {
      "start_ts": 774733
    },
    "metrics": {
      "num_uids": {
        "hours.tracked": 0
      }
    }
  }
}

Again, the 2019 query contains no 2020 entries.
