OK, I accept that in principle, but:
- is there a known error in that version which would cause it to become
unstable? As the software had been OK until last Friday, why should it
suddenly become not OK? Would the arrival of a leap second indicator
cause instability in one copy and yet other PCs continue to function
correctly? It doesn't sound right to me.
- which version would you suggest using?
- where to obtain it? Given that:
- Terje's most recent version is: ntp-dev-4.2.0a-20040319-nt.zip.
- Meinberg's is a ready-to-install package, whereas I just want .exe
files I can copy - the installation is already done.
- I wouldn't trust compiling it myself.
