evaluations of TimeML technology are available online:

   - TIMEE/TIPSem by Hector Llorens:
http://gplsi.dlsi.ua.es/demos/TIMEE/ (binary
   release)
   - ClearTk,including Steven Bethard's TimeML tagger:
   https://code.google.com/p/cleartk/ (open-source, built on UIMA)

Other tools are available for individual components of the task, such as
temporal expression recognition and normalisation (e.g.
https://code.google.com/p/heideltime/).
