i think i'd really need to have two separate levels where time runs at different speeds.
1) first level (which i'll call "the i-don't-want-it-to-arrive time"): the keyword here is "delay". for example, i don't want thursday to come because i'll have a test at uni that day.
2) second level (the so called "yes-yes-gods-of-metal-let-it-be-now"): no need to explain, on this level i want time to run faster than fastest. for example, i want thursday to be here in the twinkling of an eye 'cause on thursday i'll see my love!!
