No it's not, the upgrades, just shorten the time by paying tokens, Eg, Stadium 16 days reduce by 16 days cost X tokesns 10 days X and so on, the same with any facility.
Tokens talk in this game, especially when it's not you spending them, hurts a little but hey! let them get on with it, they'll meet their match one day, then have to spend a shed full more.
