How to add simple Servo code from a Tutorial?

If I follow Chris and Steve correctly, don't I use microseconds for ServoTimer2?

I'm starting with this

// import the library
#include <ServoTimer2.h>
// create an instance of the Servo library
ServoTimer2 myServo;

so if I then say myServo.write(x); shouldn't x be in microseconds? Or do I need to write this another way?
