Hi!
I was trying to buy a ticket from Zurich to Paris on the SBB website but everytime I try to insert the requested date of birth it gets changed to a day before (e.g. my date of birth is 16.11.1990 and the website automatically changes that info to 15.11.1990). I don`t see any other complaint here about this issue, why is this going on and how do I fixed it?
