Debido a un proyecto que estaba desarrollando me vi en la tarea de usar Gson y necesitaba que se pudiera enviar la fecha desde el fronend. Probe varias de  las siguientes formas :

private static Gson gson = new GsonBuilder().setDateFormat("EEE, dd MMM yyyy HH:mm:ss zzz").create();
private static Gson gson = new GsonBuilder().setDateFormat("yyyy-MM-dd'T'HH:mm:ssX").create();
private static Gson gson = new GsonBuilder().setDateFormat("yyyy-MM-dd'T'HH:mm:ssZ").create();
private static Gson gson = new GsonBuilder().setDateFormat("EEE, dd MMM yyyy HH:mm:ss zzz").create();

Pero la única que me dio resultado fue:

 private static Gson gson = new GsonBuilder().setDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'").create();
2016 IEEE Colombian Conference on Robotics and Automation (CCRA 2016)
The 2016 IEEE Colombian Conference on Robotics and Automation (CCRA 2016) follows the 5th IEEE Workshop on Robotics and Automation (IEEE CWRA) organized by the IEEE RAS Colombian chapter and IEEE-Colombia. CCRA 2016 will be held in Bogotá, Colombia, between September 29 th - 30 th 2016.
The venue for CCRA 2016 is the Universidad Sergio Arboleda.
CCRA’s objective is to gather academic and industrial Colombian robotics and automation community to discuss advances in robotics and automation, and how to transfer this knowledge into the society. Alongside CCRA 2016 there will be several robotic competitions, one of which will be the Colombia classificatory for the IEEE Latin American Robotics Competition 2016 (LARC 2016).
The proceedings of CCRA 2016 will be published by IEEE and will be available in IEEE Xplore. CCRA 2016 seeks for English written high-quality papers
presenting original results in all areas of robotics and automation, also including works in related field such as machine learning, computer vision and
control. Spanish written contributions can be submitted but will not be published by IEEE. There will be also a special track for undergraduate student’s
projects. Among other, this conference encourages contributions in the following topics:
• Agricultural robotic systems • Unmanned aerial systems • Marine robotics
• Medical robots • Swarm robotics • Tactile & haptics devices
• Educational robotics • Sensors & actuators • Computer vision for robotics
• Robotic competitions • Mechatronics • Sensing & sensor fusion
• Systems and signals • Ethical & legal robotic issues • Field robotics
• Multi-agent systems • Personal & service robotics • Human machine interaction
• Control architectures • Biomimetic robots • Locomotion
• Localization, mapping & navigation • Applied control for robots • Flexible manufacturing systems
• Path and motion planning • Distributed & networked systems • Decision support systems
• Intelligent control • Systems Identification • Process automation
