Okay, so after no on-list replies, but one off-list reply offering (likely for a significant fee) to provide a patched version that had the required feature. This implies that someone was naïve enough to assume the destination port number was never going to change. So, a work-around which I'll post here for the next person who needs this. There exists a very simple SNTP client at https://github.com/lettier/ntpclient/blob/master/source/python/ntpclient.py It is crude, but my workplace actually uses the C version of this with good results on 6LoWPAN based networks. The code in the Python version normally just returns the current time. Add `import os` to the start of the file, then replace the final `print` line with the following: ``` # Set the time os.system('date %s' % ts_val.strftime('%m%d%H%M%Y.%S')) ``` Now when called as `root` from a `cron` job, it will update the system time. There's a few additional tweaks needed to make it work on Python 3, but the gist is there. _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
