My result is 28.5 seconds. The way I calculated it:

His cooldown on ult is 108 seconds with full CDR.

His cooldown on rewind is 3.6 seconds and it rewinds it by 10 seconds. That makes it reduce the cooldowns by extra 2.7778 per second. This makes his cooldowns go down 3.7778seconds every second.

Ult's cooldown is thus reduced to 108 / 3.7778 = 28.5882. Now, to be more precise, we should make it a multiple of W's cooldown, making it 28.8. Any extra seconds are just player's reaction time and lags combined.
