Time is non-linear, we are in the 4th dimention.

Also its usually 1 digit of time left of the decimal point on the countdown timer. Usually like 3 seconds or less, sometimes they make it so dramatic that its literally last second or fraction of a second.

Like... c'mon. Make it so at like 23 second left, or 1 minute 47 second left or something random, like every bomb always get disarmed at 1 second? The fuck lol.
