If I'm not to late to this, how would a thief of time abuse their powers?

If they do not want to do an activity or bear someone nagging at them, they could Steal Time- Making it skip and seemingly fast forwarding through a rant or making someone think they’ve been doing something for so long they lost track of Time, thus stopping them on their tracks, or literally skipping through something boring, long and tedious without actually having to do anything.
