$prog groupname new_time_played
where:
    groupname is a game group such as silly or educational
    new_time_played is a new amount of time played for that group, such as 1800
For example, you could have the group educational have already had 1800 seconds
playing time with:
$prog educational 1800

To reduce the time played to minimum (i.e., allow the maximum playing time), do
$prog educational 0

This will also take care of changing the date to today,
to make that limit current.

Better to use change-game-time-left.sh, since it is more user friendly.
