[atlas] Weird connection reports at DST switch day

Hello.

I recently noticed weird entries under last connections in web
interface. Strangely, in Europe, DST change was at same time. But it
should be always using UTC like it mentions?! Maybe some systems there
isn't fully UTC... I have real problem connecting that info with april
report of probe. Simply doesn't fit. Mail report says it was connected
30d in march, connection log says that it was disconnected for 23d in
march... There are only 31 days in that month :)

Take a look at URL:
