I'm a French native speaker, so my OS interface (GNU/Linux Xubuntu) is in French
Thus, when I plot a time series using Matplotlib with datetime as X data, the returned plot have the months written in French
How can I obtain those printed dates in another language (typically English) ?

Using the DateFormatter module from matplotlib, you can specify the format that you want to use for the date using the syntax: "%X %X" where each %X element represents a part of the date as follows: %Y - 4 digit year with upper case Y. %y - 2 digit year with lower case y. %m - month as a number with lower case m.
Ticks are the values used to show specific points on the coordinate axis. It can be a number or a string. Whenever we plot a graph, the axes adjust and take the default ticks. Matplotlib's default ticks are generally sufficient in common situations but are in no way optimal for every plot.
MatPlotLib with Python Position and labels of ticks can be explicitly mentioned to suit specific requirements. The xticks() and yticks() function takes a list object as argument. The elements in the list denote the positions on corresponding action where ticks will be displayed.
You can set the desired location/language using the locale module. To get English, try setting locale to en_US.
EDIT:
In bash on Ubuntu, you may need to use en_US.utf8
In [1]: import datetime
In [2]: import locale
In [3]: locale.setlocale(locale.LC_ALL,'fr_FR')
Out[3]: 'fr_FR'
In [4]: datetime.datetime(2015,7,1).strftime('%B')
Out[4]: 'juillet'
In [5]: locale.setlocale(locale.LC_ALL,'en_US')
Out[5]: 'en_US'
In [6]: datetime.datetime(2015,7,1).strftime('%B')
Out[6]: 'July'
Using tom's answer and the post hereafter, the local settings for an Ubuntu-like OS are :
import locale
locale.setlocale(locale.LC_ALL,'en_US.utf8')
The list of available languages can be obtained in the terminal with
$ locale -a
