Recommend a Good 5 minute timer?

Can anyone recommend a good but simple 5(long) minute timer?

Something to play around with.

make a timer, set the interval to 60000, so 1 minute

in the timer:

timer1.tag = val(timer1.tag)+1

if timer1.tag >= 5 then
timer1.tag = 0 'reset timer
'timer code
end if
