CFUserNotificationDisplayNotice Timeout bug?

I'm experimenting with CFUserNotificationDisplayNotice function and 
have found the timeout period is inaccurate. If I pass 1, 2, 3, 30 or 
40 seconds into the function it takes about 20-30 seconds for the 
dialog box to be displayed. Am I missing something obvious, or is 
this a bug?

CFUserNotificationDisplayNotice(1, kCFUserNotificationNoteAlertLevel, 
NULL, NULL, NULL,CFSTR("My App"), CFSTR("This is a test error 
message."), NULL);

Thanks.
