Galician date and time localization

I would like to request a little modification for Galician date and time localization. As of today, format is as follows:

time, data (hour:minutes, day de month de year).

A more accurate format for Galician would be:

data ás time (day de month de year ás hour:minutes)

i.e., moving time to the end and adding the word "ás" between date and time (something similar to French).

I suppose this is to be posted on BugZilla. Is it right?

Yes, please. We'd like to have a more formal trail of this type of changes.

 Done. Bug #41295.
