Thank you, I will put a query on Github.

However, I think they've used code from NetTimeLogic under a licence [1][2] that precludes distributing the source:

> 3.2 Distribution Rights. LICENSEE may reproduce and distribute the Licensed Materials, solely in binary form that operates in LICENSEE’s system-level hardware products.

This is a perfectly reasonable way of developing a system but it is sadly incompatible with sharing your work as open source.

Edit [2] IANAL, this is not legal advice etc.
