Yes you can and here's an example :
aTimer = setTimer (
function ( )
outputChatBox ( 'Timer End' )
end,5000,1
)
addCommandHandler ( 'data',
function ( )
if aTimer and isTimer ( aTimer ) then
local remaining, executesRemaining, totalExecutes = getTimerDetails ( aTimer )
outputChatBox ( ' #FF0000'..executesRemaining..':#0000FF'..totalExecutes..':#FF00FF'..remaining..' ',255,255,255,true )
else
outputChatBox ( '* The timer doesnt exists.' )
end
end )
