intermediate catch event timers

In this scenario, there are 2 intermediate catch event timers in sequence, in which the first timer has timerEventDefinition with timeDate value calculated in a java method (java.time.LocalDate.now() + 3 days), and the second timer is calculated with (java.time.LocalDate.now() + 5 days). The question is related with the 2nd timer timeDate calculation. Assuming that the process instance starts on day x with a start event, which is the timeDate calculation date for the second timer? According to the scenario above, will it be (day x + 3 days + 5 days), or (day x + 5 days)?
