Time indicator not localized after installation in a non-english language

[Jean-Baptiste Lallement]

Ubuntu Trusty Desktop AMD64 20140414

TEST CASE:
1. Boot from a desktop ISO
2. In ubiquity-dm, select 'Deutsch' then 'Ubuntu Installieren'
3. Proceed with the rest of installation, keeping the defaults (In my case ubiquity preselects 'Paris' for the timezone and a French keyboard layout)
4. Reboot after installation and login

ACTUAL RESULT:
Most of the desktop is in German but the time indicator is in French

EXPECTED RESULT
Time indicator should be localized

Output of locale:
LANG=de_DE.UTF-8
LANGUAGE=de_DE
LC_CTYPE="de_DE.UTF-8"
LC_NUMERIC=fr_FR.UTF-8
LC_TIME=fr_FR.UTF-8
