When you are login as an email user, on the date column, the date the email was sent to you will be shown as the following format depending on how old it was.

If the email was sent  today: Today 14:57
If the email was sent within the last week: Tue 7:35
If the email more than a week old: 2013-6-13 7:35

Which settings/config files do i edit if I want to change them to the following format?

If the email was sent  today: Today 2:57 PM      --------> not 24hr format but 12hr format
If the email was sent within the last week: Tue 3:03 PM   -------> not 24hr format but 12hr format
If the email more than a week old: 06-13-2013 7:35 AM  or Jun-13-2013  7:25 AM --------> it would be better if it is the later, and the time should be 12hr format indicating AM or PM

Thanks in advance.
