How to determine last message received on websphere mq queue

I have around 1.2 million messages on a queue.
I want to check when the test completed. The time when the last message was put to the queue would give me this information.

MQ Explorer only displays 500 msgs.
RFHUtil has a browse function, but it starts from the first msg.

So, can anyone tell me, using either RFHUtil, runmqsc or MQ Explorer, how I can browse the very last msg on the queue?

Well you finally realized that a queue is not a DB. good for you!

Now there are tools that will allow you to find out the answer to your question: example mqmonntp or MO71.
However this will still take quite some time as all messages still need to be browsed.

You'd be better served by checking at what time your sending application finished the puts and did the last commit. (1st choice)
