Answer 1

You can define Timer Events with "Time Cycle" (periodic) or "Time Date" (one time) triggers
If you use "Time Date" (one time) trigger, you can specify any Simple Expression that returns a DateTime . Like for example:
'now' + '30m'
dataObjectTime + '2h'If you use "Time Cycle" (periodic) trigger, you can specify any Simple Expressions that return an Interval/Duration . Like for example:
'1h30m'
dataObjectInterval
dataObjectInterval + '30s'
