I am trying to use
this plugin for TW that adds the vis.js timeline feature. However, the dates I want to put on my timeline start around 1600 BCE. I can't seem to get it to accept any format for this and have had no luck finding documentation that solves my problem.
This is the developer's github but I don't have much experience with github – is there a way to contact people directly (is that even socially acceptable)? It seems that plugin is using the moment.js libraries to parse the dates. The plugin seems to allow us to easily change the format the library is parsing but I can't seem to find a conclusive answer to if there is a way for this library to handle BCE dates.
Any ideas?
