Very nice! I liked how the broken up lines made the time aspect more prominent. The line "One minute it flies" is read quickly, while "The next" and "It drags" are broken up to make it take more 'time'.

I would like to suggest a little rewording to the end stanza. I think it'd sound a little better if instead of "The right to control it" it said "Control over it". Also the line "Until that day" could be changed to "Until then" since the poem already uses "day" in the first sentence of the stanza "Someday".

All in all I thought it was a nifty piece :) 8/10
