If you want to use parts of chrony in non-free software, you will need to use
older versions of the source code. Alternatively, contact me - I may be
prepared to licence parts of the source code to suit your purposes. I am quite

licences, as well as to commercial projects which are of a single-customer
"turnkey" nature (as opposed to mass-market "shrink-wrap" or "floating-licence"
products).
