commit c6142232851e5dfef008b336a6e2adeb382988f4
Author: Jérémy Bobbio <lunar at debian.org>
Date:   Tue Dec 30 21:15:57 2014 +0100

    Add SetModificationTime function to scripting languages
    
    For font compilation to be deterministic, we need a way to set the font
    modification time to a defined value instead of the current time.
    
    We thus add a new function “SetModificationTime” to the scripting language.
    It takes a single string argument looking like “2014-12-30 21:18:33”.
    
    We also add the corresponding “setModificationTime” method to the
    Python bindings.
    
    Closes: #774274
