To accomplish this you would need to create a new User-Defined Property and set the current time as value. In the following example I have created a new Rule Set in which I first set the time zone to UTC + 2 and then write the current time in my user-defined property "User-Defined.CurrentTime". Please note, that we need to set the time zone in order to calculate the current time.
Now you can use the User-Defined Property in your Criteria and build a rule like this:
You may want to create a new rule set and use this criteria for the rule set instead of just a new rule. But this is up to you
Thank you very much for the help.
