To have "time on your hands" is an idiom that means simply you have time in which to do anything you like. Time, of course, cannot be held in the hands, so the word hands is a metaphor which means to have, or to possess. An equivalent expression would be "I have plenty of free time."

it's late and i forgot about this project and i'm really not feeling any creative or clever these days. you will excuse me for being so, won't you, as hopefully it is just temporary.
you are totally excused - and in any case, you are always creative - and always interesting. Little blue appears to be in tip top condition despite his antics you must be looking after the keeper of time very well.
I wanna have time on my hands too. Every time I try to grab time like this, it sprouts legs and runs away! :P I always enjoy the creative shots you make with time. :D
