Synchroniziny Animations

[Redman]

Hi,

I have some rectangles that start blinking (SequentialAnimation with border.color changes) depending on some condition.
Is there some global timer or something like that to which I can hook the animation to start?

Right now if condition is met for rectangle1 it starts blinking. If 2.5s later the condition for rectangle2 is met it also starts blinking.
They are not synchronized.
I'd like to let them both blink at the same time.
