No sntp time source was available if I remember correctly, only novell clients and servers, possibly a sco server several (isdn!) hops away. Details are hazy now and I don't have access to the notes anymore since I switched work some years ago, but I remember we had to live with an unsynced clock and use the old "now the router says it's x o'clock so that log is really from y o'clock" differential timing :(. I think at that time on the remote network were only old netboot msdos novell clients and we could not bring up the isdn line in order to sync the clock or something like that. Hmm can't be, it would have synced happily with sntp at least whenever the line was up, there must have been some other reason. Possibly incompetence on our side :)
