Czech Republic - Olomouc

This cover from the Czech Republic has an extra number making the date stamp 12.12.12.12. I don't actually know what the extra 12 is for - perhaps this was mailed at 12 o'clock on December 12, 2012?

The stamps used on the cover were issued on November 7, 2012 featuring images from Ctyrlistek in the King's Service. Ctyrlistek is one of the most popular children's comic books first published in 1969.

To make up the postage, the sender also used a 1Kc stamp from the May 9, 2007 flowers issue.
