I'm sure I've pissed off the Time-Trolls. They're the little demons who set my alarm clock so it goes off an hour early. Or not at all. They're the creeps who cause me to be 10 minutes late for work, a job interview, miss a flight.
Considering how we live and die by the clock, the Time-Trolls are guys you definitely don't want to mess with. "In the Time-Trolls' Sinister Clutches" is drawn by Mike Sekowsky, from Beyond #11, 1952.
