getTime() function and synchronisation with sound

I use the mc_Tween functions by Zeh Fernando. These functions run in time and time is a parameter you give to the functions for duration of an action being completed. My question is now:
If the actions (for example tweenings) are synchronised with sound on my computer, are they synchronised in other computers as well?
I mean if I publish this flash work on the internet, every user experience this synchronisation?
