O.K., the answer for the second question I found in " whats new 1.3.5." . It is not from super orders but from the zen-cart release.
"Bugfix: CC module no longer stores full CC numbers"
So I will try the cc-module from 1.302 because I don't want to type the numbers always by hand. I can delete the numbers after charging the card. But please help me with my first question, the time zone offset.
