[arch-general] Mirrors not synchronized or a problem with the package database?

Is there a problem with the mirrors and their synchronization or with the package database? Since a while pacman tells me that my package databases for all repos are up-to-date. The latest version of linux in those databases is linux 3.3.6-1 while the latest version in [core] should be 3.3.7-1 according to the online package database at https://www.archlinux.org/packages and the ABS. This happens with every mirror in my mirrorlist. According to the mirror status at https://www.archlinux.org/mirrors/status/ they are all up-to-date and 100% complete. Of course, I already did a pacman -Syy, but this didn't help. Heiko
