Hangfire dashboard, change date and time format?

Is there some way to specify what date and time formats to use?

Currently i send the following header Accept-Language: sv,en-US;q=0.9,en;q=0.8 but i still get AM/PM time. (In Sweden we use 24H clocks) i have also tried sv-SE,sv;q=0.9,en-US;q=0.8,en;q=0.7 but that did not help.
