Date displayed has usabilility issues

is there any way to change current configuration on how the date of a post is displayed? currently we have an usability issue here:

as you can see in the image, the date is displayed without year information and the title attribute has a different value.

@hvelarde , Apr'15 is (admittedly english-centric) shorthand for April 2015. So there is info missing in the short version, but it's the day that's missing. For posts over a year old, that can be a defendable choice if screen real estate is at a premium.

Not sure it can be easily changed
