That code is inconsistent in terms that you remove the ESP connections directly whereas for the time-based choice you use a :foreach; worse than that, the foreach alone doesn’t save you from the script stopping on first error (a connection disappearing spontaneously before you remove it), you need the :do … on-error construct to ignore such events. But that’s not the essence.
Have you seen (or even tried) this?
What exactly do you mean by “this”?
