Ok this probably sounds really strange,  but i'm trying to change the time format to 12 hour (not very good with 24) , and for some reason I can't get it to do it. I've tried going into International - Formats - Customize, and although i've changed it and it looks like it's showing 12 hour in the preview, it isn't actually on the toolbar  Any help would be much appreciated.
  Any help would be much appreciated.
