Problem on timming

Hi all,[INDENT] What I want to do is, I have a movie clip on my flash move. At the beginning I set its ‘visibility’ to ‘false’. What i want to do is, when I call a method, visibility turns to ‘true’. After 4 second again visibility turns to ‘false’.

Script to turning visibility status is ok. But how can i count 4 second inside action script?

Thank You!
