Well, my code uses handlers, which are specific to android, so at least I
thought I'd post my code,
so anyone with any comments on this android-specific code feel free to drop
me a line.

class TimeStampedMessage {
TimeStampedMessage(Handler handler, long when, int what) {
this.handler = handler;
this.when = when;
this.what = what;
this.timeStamp = System.nanoTime();
}
static void pauseTimers() {
for (int k = 0; k < TimeStampedMessage.timeStampedMessages.size(); k++)
{
TimeStampedMessage timeStampedMessage =
TimeStampedMessage.timeStampedMessages.get(k);
long oldTimeStamp = timeStampedMessage.timeStamp;
long newTimeStamp = System.nanoTime();
System.out.println("When1: " + timeStampedMessage.when);
System.out.println(oldTimeStamp);
System.out.println(newTimeStamp);
timeStampedMessage.when -= (newTimeStamp - oldTimeStamp) / 1000000L;
System.out.println("When2: " + timeStampedMessage.when);
timeStampedMessage.handler.removeMessages(timeStampedMessage.what);
}
}

for (int k = 0; k < TimeStampedMessage.timeStampedMessages.size(); k++)
