Time Busters is a British children's television series created by Tim Child and the same producers of Knightmare.
Each run of the game involves a team of children taking a 'time-travelling' bus that drove you to a historical reenactment.
The children would be involved in a quest to find a Time-Capsule.
[1] This challenge would be a race against the clock to succeed and each episode would result in the team being successful, or having to abandon their attempt due to running out of time.
Regardless the episode would conclude in the children quickly returning to the bus before it disappeared from that era.
