When I went in at 18:41:00 (UK time) 31/07/2013 my total confirmed and unconfirmed was 0.17885167
in again this morning just now 06:16:00 01/08/2013 total confirmed and unconfirmed is 0.17826633

during the night the meter has been running backwards for me, and yet I don't see anything in stats in terms of invalid blocks

any ideas? We're not talking a huge amount here, but is potentially lost work during the night
