Event dates not translated in some cases

Problem/Motivation

Hello,
I've a site in Catalan language. I can see events with the translated "date start" and "date end", but only when the difference between dates is different than "month".

Commons events shows event dates in different formats depending on the difference between start date and end date.
For example (in catalan language, cause is the example I have):

dilluns, 23 febrer, 2015 - 15:00 - 16:30
dilluns, 2 març, 2015 fins a dijous, 12 març, 2015, 17:00 - 22:00
divendres, 13 febrer fins a dissabte, 14 març, 2015, 09:15 - 09:15

All this logic is done in commons_events module, but it is not taking in account the language for some use cases.

Proposed resolution

Looks like theme_commons_events_date_display_range_advanced() is using format() function from date module, but format() function is not language aware.

I've attached a patch that uses date_format_date() and date_limit_format(), getting the same funcionallity but language aware.

If you can test it, it will be great.
thanks.
