Hope this helps.

First create the timer and then you can cancel / pause / resume it.

local myTimer = timer.performWithDelay( 1000, myFunction )

Then later:

timer.pause(myTimer)

Read the documentation with included examples @ http://docs.coronalabs.com/api/library/timer/index.html [import]uid: 177091 topic_id: 31619 reply_id: 126291[/import]
