setting date format in menubar on top of desktop

How do I change format? When I open "time & date settings" I find very limited possibilities. So is there any file which sets my date format in clock shown on top of screen? The only thing I need is just change order of values (I don't want to have week-day/MM/DD/YYYY hh:mm:ss). And second my question: is it possible to set different font colours for values in it? for example first colour for month and year, and second different one for hh:mm:ss ?

Solution 1:

With the dconf editor, set com.canonical.indicator.datetime.time-format to custom and com.canonical.indicator.datetime.custom-time-format to whatever format you want to use.
