"Time" in actor's attribute

Oxygen

hello there !
I want to know what is the "Time" attribute in actors for?
I saw some tutorials on how to make an actor follow a path like perfect circle or wave but i don't understand the use of the "Time" attribute.
Can someone explain me please?

thanks

Time is just the time an actor how been in existence for. It constantly counts up from when he actor enters the game
