Comment (by arthuredelstein):

 OK, I can reproduce this on Ubuntu 14.04 LTS. In the web console, I can
 also generate localized strings with
 English-US:
 `new Date().toLocaleString();` -> `"Mon May 12 18:01:49 2014"`
 `new Date().toLocaleDateString();` ->  `"05/12/2014"`
 vs German:
 `new Date().toLocaleString();` -> `"Mo 12 Mai 2014 18:04:56 UTC"`
 `new Date().toLocaleDateString();` ->  `"12.05.2014"`

 I'm not able to reproduce this on OS X.
