I am perfectly happy to sell anyone who wants one a Rasperry Pi in a big heavy metal box. I'll stick 'SUPER ACCURATE NTP SERVER' on the front, and you just need to plug it in. I think AUD$1000 ex GST sounds acceptable. Please form an orderly queue to the left. For an EXTRA $800, I'll stick a GPS Time source in there, and it can be a Stratum 1 time server, rather than Stratum 2.
(Yes, this is humour. If someone REALLY wants to do this, please contact me off-list, and I'll happily step you through it - you're looking at less than AUD$100 in hardware to create a Stratum 2 NTP server) On Sat, 2 Feb 2019 at 11:54, Mark Smith <[email protected]> wrote: > > On Sat, 2 Feb 2019 at 12:35, Michael Junek <[email protected]> wrote: > > > > Thats correct.
