I am living in Europe. On our AppleTV and in the Webinterface times are in 24h format.
On our FireTV in the Guide header the time is shown as 12h format with german words for forenoon and afternoon.
For example now (21:32) it showing 9:32 nachmittags, which is totally odd as 9:32 is morning or evening, but not afternoon 
In the insert when watching LiveTV it is showing 9:32 without suffix.
I want the FireTV to also use 24h format as the other devices, but i cannot find an option to configure it.
Maybe this is bug or did i do something wrong?
Thank you for help.
