From the table above the only one that matches it is the second one.
Some European guys weren't able to play yesterday evening (maintenance was on) so, I suppose, UK data are wrong for the 1st, 3rd and 4th maintenance periods. If we assume simultaneous downtime worldwide the time seems fine (they all end at the same time) but the date is wrong, it should be the day before.
