Should be an option to switch to 24h time format in chat window
Many countries (Europe) are using 24 hours time format, so it's not convinient to have only 12h format in chat window. Marking it as Major, because simple users would complain a lot about such "simple" design things.
It works fine with ordinary messages. But "contact is going online/offline" still shows 12h format.
probably Spark should use locale settings to determine correct time format
