Hi Jayani, There are several enhancement engines in Stanbol developed based on OpenNLP. (opennlp-ner, opennlp-sentence, opennlp-pos...See [1]) Each of these engines focus on a particular enhancement aspect using OpenNLP. Therefore I think it's better to write a new engine for temporal extractions rather than extending the OpenNLP-NER engine.
