show month in words(Jan, Feb, Mar)

[GoogleCodeExporter]

What steps will reproduce the problem?
1.$start = date('Y-m-01', strtotime('-1 month'));
2.$end = date('Y-m-d', strtotime('-1 month'));
3.

What is the expected output? What do you see instead?
I want the month to appear shortened. Instead, the numbering of months appears 
in its place. When replacing 'Y-m-d' by 'Y-m-d' the following error appears: 
"Invalid value for end-date parameter".

What version of the product are you using? On what operating system?
EasyPHP 5.3.1.0, last ga:pi() and Windows 7 Ultimate x64

Please provide any additional information below.

You should leave this formatting to 'Y-m-d'.
You can change the output (formatting of the results) with 'Y-M-d' (which 
returns 2013-Nov-25) etc. But the query must be in the original format I 
believe.
