TicketEscalationSuspendCalculate() expects cron time to be four minutes

[bschmalhofer]

In Kernel::System::Ticket::TicketEscalationSuspendCalculate() there are these lines:

    # add 4 minutes (time between cron runs) if we are in suspend state to prevent escalation
    if ( $Param{Suspended} ) {
        $UpdateDiffTime += 4 * 60;
    }

It is not obvious where those four minutes come from. In OTOBO the default cron interval is five minutes,

The relevant time is the configured in the setting Daemon::SchedulerCronTaskManager::Task###RebuildEscalationIndex.
I added a comment in Kernel/Config/Files/XML/Ticket.xml stating that the four minutes are relevant and should not be changed.
Marking this issue as 'invalid' and closing it.
