automation - Execute task if tasker profile has been active for some time

How can I execute a tasker task only after a certain condition has been true for a certain time?

Normally a profile executes its task as soon as all conditions are met. I want to delay this activation, until the conditions have stayed true for some time.

E.g.

• do something after the screen has been continuously off or on for 10 minutes


• do something after wifi xy has not been near for 10 minutes


• do something after cell towers x,y,z have not been near for 10 minutes.
