when running the following query, one can see that earlier block heights have a later timestamp value than blocks that come after  
cross referencing against polygonscan shows that the values are indeed incorrect. scope of problem is unknown

```auto
{
  ethereum(network: matic) {
    blocks(height:{between:[18279190, 18279192]}) {
      height
      timestamp{
        iso8601
      }
    }
  }
}

```
