Timestamp of pulled emotes is incorrect

[IronFlare]

When subscribing to an EventStream for the emote_set.update event, I am able to receive events as intended for emotes that are pushed, updated, and pulled. However, specifically on pulled emotes, the value of old_value.timestamp is wildly incorrect. Examples are shown below.

Given that there's no documentation describing special behavior for pulled emote timestamps, I assume this is in error. Do you have any idea why this might be occurring, or a temporary workaround to obtain the proper timestamp?

Edit to add: I also would have expected there to be a timestamp value for the pulled update itself as well, but the endpoint doesn't appear to provide one. I think this is a separate—albeit related—issue, though.

Sample pushed array:

"pushed": [
  {
    "key": "emotes",
    "index": 424,
    "type": "object",
    "value": {
      "actor_id": "omitted",
      "data": {
        "animated": true,
        "flags": 0,
        "host": {
          "files": [
            // Omitted for concision
          ],
          "url": "//cdn.7tv.app/emote/61c4ed2345ea0fdc58f68e8f"
        },
        "id": "61c4ed2345ea0fdc58f68e8f",
        "lifecycle": 3,
        "listed": true,
        "name": "programming",
        "owner": {
          // Omitted for concision
        },
        "state": ["LISTED"],
        "tags": [
          // Omitted for concision
        ]
      },
      "flags": 0,
      "id": "61c4ed2345ea0fdc58f68e8f",
      "name": "programming",
      "timestamp": 1693865677849 // <---- Correct value
    }
  }
]

Sample pulled array, for an update executed moments later:

"pulled": [
  {
    "key": "emotes",
    "index": 424,
    "type": "object",
    "old_value": {
      "actor_id": "omitted",
      "flags": 0,
      "id": "61c4ed2345ea0fdc58f68e8f",
      "name": "programming",
      "timestamp": -62135596800000 // <---- Incorrect value
    },
    "value": null
  }
]
