I never have any idea how much time has passed. Also useful for something that can go on indefinitely like trying to pick a movie - at the end of ten minutes a decision must be made.
Unlock new time. And if you're anything like me where it takes a while to adjust, โOh dear, it's 19 oโclock.โ stops me in my tracks and I get to figure out what time it is. Every time past 12. Time slows in those moments.
