How do I add timer count in game

I am planning make game with time counting, so if player begin the game, the timer is counting up, it's mean more player playing game, the more time will display, this mean how much time the player play game, the result is the most player shorting play game, there are the winner

So what is the question?

try something like

create a variable named 'time'

create a vairible named 'players'

____for every player add one to players variable

every second event and do 1 divided by players

____add 1 to time variable action

create text object and place somewhere visible on layout

do every tick event

set text of object to time variable
