I reported this in the pst several times....
Product and version since, I think Version 8
OS and version
Browser and version (for WebDirect only)
The date format 13/1/2016 is wrong formatted for switzerland, correct would be 13.1.2016
How to replicate
Auto enter date in a field, shortcut, there are many ways....
Workaround (if any)
reformat every single used date since over 10 years.....
Would be great if this would be fixed after such a long time....
