what is View.getDrawingTime()?

Question

I'd like to use View.getDrawingTime(), however, I am confused as to the value the function returns.

in my app, getDrawingTime() returns something along the lines of 545366733 Compared to System.currentTimeMillis() I see 1375750319462

The documentation is fairly inadequate in this case : http://developer.android.com/reference/android/view/View.html#getDrawingTime()

How can I compare the value I get from getDrawingTime() to currentTimeMillise() (or something similar) ?

I desire to know the time difference between now and the last time the view was drawn.

Thanks !!

I didn't dig far enough to be 100% certain, but I got to 99.7%.

Both scheduleDrawable() and the internal fadeStartTime use the SystemClock.uptimeMillis() clock. My guess is that getDrawingTime() does too.

Note that SystemClock.uptimeMillis() does not count time when in deep sleep. So, if you're trying to time events between sessions, you might want to try something else.

An alternative is to override your View's onDraw() and set your own timer, but it's up to what you need, really.
