I run the game in english, like my steam for various reasons. My windows although is natively on german. The entire "Time" col uses a german date/time format.

It says e.g. 22 Juni 2014, 18:22, but in an english client I would expect it to say at least 22 June 2014, 18:22.

I guess it uses the local date/time formatting of the OS and does not account for different language settings.
