> Thank you for your support, but unfortunately that doesn’t really help me. how can I easily add 90 minutes to the current timestamp of better logic “timeshort”? what variables do I need for this etc.? in your example only the values are set but not added. can you make me a very short advanced flow? do you have experience there?

Use the BLL Expression card and it will give a token:

```auto
date('shorttime', now+(90*60000) )

```

If you need it in a variable, use the Set Variable to BLL Expression flowcard.
