The two other options would be to use a runtime field, dissect the data away, and store a field timecontrol_base and timecontrol_increment with the information. Don’t forget to set the type long.

if (custom != null) {   

    emit(Long.parseLong(custom));

}

Timecontrol_increment:

String custom=dissect('%{}+%{custom}').extract($('timecontrol', ''))?.custom;

if (custom != null) {   

    emit(Long.parseLong(custom));

}

Don’t forget to use the formatter at the bottom and select duration, then seconds. This creates a human-readable interpretation!
