code_interface, compile time vs runtime

if this were a code_interface, is timestamp captured once at compile time and all future calls use that compiled timestamp value? If yes, is there a different way to solve this? I've got multiple live views calls this code_interface and I'm wanting to keep all the logic in one place 
      define :get_budget_with_accounts,
        action: :read,
        get_by: [:id],
        default_options: [
          load: [
            :total_balance,
            accounts:
              App.Finance.Account
              |> Ash.Query.load(:balance_as_of, timestamp: DateTime.utc_now())
              |> Ash.Query.sort(:identifier)
          ]
        ]
      define :get_budget_with_accounts,
        action: :read,
        get_by: [:id],
        default_options: [
          load: [
            :total_balance,
            accounts:
              App.Finance.Account
              |> Ash.Query.load(:balance_as_of, timestamp: DateTime.utc_now())
              |> Ash.Query.sort(:identifier)
          ]
        ]
Solution:
i.e default_options: fn -> ... end

timestamps would be captured at compile time The only way to solve it would be to make it also accept a function.

compile time, got it. I was seeing weird behavior with balances and suspected that might be it. Thank you!

This would likely be a very easy PR to make if you're interested 😄 with that said, if that is coming from ash_double_entry I think it defaults to now inside the calculation?

i left off timestamp: DateTime.utc_now() and saw the same behavior.

hmm... oh yeah thats a weird one because it sets the defaults when you load 
      define :get_budget_with_accounts,
        action: :read,
        get_by: [:id],
        default_options: [
          load: [
            :total_balance,
            accounts: Ash.Query.sort(App.Finance.Account, :identifier),
            accounts: [:balance_as_of]
          ]
        ]
      define :get_budget_with_accounts,
        action: :read,
        get_by: [:id],
        default_options: [
          load: [
            :total_balance,
            accounts: Ash.Query.sort(App.Finance.Account, :identifier),
            accounts: [:balance_as_of]
          ]
        ]
but yeah making that accept a function would be good.
