Hmm, I'm actually 1yrraLgmRZ1fbgtz2BSVXcWVrJnH785QZ—I received exactly .00012807 BTC on this address.
And indeed, I was mining during the entire last several days, as far as I know.
Edit: I just checked, and it turns out I very briefly mined using 1Q68UdKBYgBVy7h4gAAXcipaoBPeoJZrXQ at the beginning. This was for a very short period (no more than a few hours or so), then I switched to the address I mentioned above for the remainder of the time.
The first share I see from you is timestamped Tue, 18 Jun 2013 00:24:04 GMT (to the 1Q address, the first share from 1yrraL was Tue, 18 Jun 2013 01:23:08 GMT)
The 5th block was found 2013-06-18 00:55:45 and the others were found on the 17th, according to
https://blockchain.info/address/1B1kSM3KfcP9BvGDC1G3cxZAV9LbxovpQiAs for shares since then, here is why I am expecting if a block were paid out now:
Total Payout: 0.155

Is that more in line with your expectations? Do you disagree with either the timing of your mining or the blocks (I don't see anywhere where it specifies it is using UTC, but it appears so).
