See the Blink bug I filed here: http://code.google.com/p/chromium/issues/detail?id=233977

Steps to reproduce the problem:
See the test case URL.  This test case creates a context, waits for half a second, then initializes a gain value increase from 0 at time 0 to 1 at time 1, and then starts playback.  The current time reported in the first play() call is around 0 but it should be around 0.5, and the computed gain value is wrong as well (it should be around 0.5).  Similarly for the second call to play().

What is the expected behavior?

What went wrong?
See above.
