Having issues scheduling an automaticAppDiscount mutation

Hello I am trying to use the startsat and endsat properties of an automaticAppDiscount mutation to schedule the discount. Here is the mutation I am using:

mutation {
  discountAutomaticAppCreate(
    automaticAppDiscount: {title: "Test2", functionId: "##################", 
      startsAt: "2024-08-22T13:55:00.000Z", combinesWith: {shippingDiscounts: true}, endsAt: "2024-08-22T14:00:00.000Z"}
  ) {
    automaticAppDiscount {
      discountId
    }
    userErrors {
      field
      message
    }
  }
}

However the discount only ever shows up as expired and never enables. Is this because of the short testing window or am I incorrectly setting those fields.

Thank you for any help!

This is always UTC time and I misread the documentation.
