How Europeans count: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12
How Americans count: 12, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11
So it's 12 PM, not 12 AM, but don't be surprised if you see someone make that mistake, 12 AM and 12 PM are pretty difficult either how and certainly for non-American who aren't taught the (illogicality of) the system in primary school.
Also note that it's actually GMT+2 because of summer time (or daylight saving time as Americans call it). (edit: as wakanarai already said 2 posts before.)
