Cancelling ACH/Bank Account Payments

Is there a cutoff time for cancelling ACH/Bank account payments?

The batch cut-off time is 9.30 pm EST.  So, ACH payments will be available for canceling until 9.30 pm EST.

For example, Payments taken from 9.31 pm EST on Monday until 9.30 pm EST on Tuesday will be available for cancellation until 9.30 pm EST. on Tuesday.
