[TIMOB-9705] TiAPI: Titanium.Media.Sound.time units should be consistent between platforms

Current playback position of the audio.
On iOS, playback time is reported in seconds.
On Android, time is reported in milliseconds.

	return {

		},
		shouldBeGreaterThan : function(expected) {
			if (actual <= expected) {
				Ti.API.info("expected greater than: <"+expected+">, actual: <"+actual+">");				
			}
		},
		shouldBeLessThan : function(expected) {
			if (actual >= expected) {
				Ti.API.info("expected less than: <"+expected+">, actual: <"+actual+">");
