Unable to understand Javax Clip setMicrosecondPosition. What am I missing?

Question

I am adding a minute (60*1000*1000 microseconds) to the audio clip and starting it and I achieve the desired result only the first time i.e, I'm reaching the correct point in audio file. Next time I call getMicrosecondPosition on the Clip object, I get the microsecond position as if I didn't add anything. Have attached the sample snippet and output for this behavior. Can't quite understand what I'm doing wrong.

clip.stop();
currentPlaybackTime=clip.getMicrosecondPosition()+60L*1000*1000;
System.out.println("Playing from "+currentPlaybackTime+" ms i.e "+currentPlaybackTime/1000000.0+" seconds");
clip.setMicrosecondPosition((currentPlaybackTime));
System.out.println("Verifying: currentPlaybackTime is "+clip.getMicrosecondPosition());
clip.start();
System.out.println("Verifying 2: currentPlaybackTime is "+clip.getMicrosecondPosition());

Output is

Playing from 63326000 ms i.e 63.326 seconds [Note:this is seeking to correct point in audio file!]
Verifying: currentPlaybackTime is 3326000 [Why not here?]
Verifying 2: currentPlaybackTime is 3326000 [and here?]
