How to find time in milliseconds?

How can I find time in milliseconds? I would like a float value, not an int.

Thanks

EDIT: By time in milliseconds, I mean how many milliseconds have passed.

Time.time * 1000;

To find the time that has passed, you can use Time.deltaTime in your Update() method.

Time.deltaTime gives you the time that has passed in seconds. To get the milliseconds, simply multiply by 1000.

float timeChangeInMillis = Time.deltaTime * 1000;
