We don't actually know how Clock Up work's actually.
Some think it move's you into another Dimension where everything moves at the speed of light (Or close to it), some think it does stuff with time, and some just think it makes you go bullshit fast.
The Worm's themselves did it with their metabolism or something and the system was supposedly based on what they did, so...
Hyper Clock Up make's you go so fast you outpace light and time start's slowly going backwards.
Though I'm fairly sure one of the Red Ranger's had super speed to, I just can't remember which one, though apparently nowhere near the sheer ludicrousness of "The Rain stops falling" or "The entire battle lasted less time then it took for a bottle to hit the ground" or "I stabbed it six times and Rider Kicked it in the time it took a bullet to travel four feet".
Of course, <a href='http://tvtropes.org/pmwiki/pmwiki.php/Main/EvasiveFightThreadEpisode' target='_blank' rel='nofollow'>all speedster's go the same speed, no matter what how fast they are, so...</a>
