I OK, I get the idea of synchronising the clocks of different hosts on a network, and I think it is quite useful... BUT: I know, that PROGRESS Database eg is *very* allergic against changes in the system time. Especially setting the time BACKWARDS (even 1 sec) will kill the server/broker process, because database integrity is based on the time. There is a network version of PROGRESS around ( which I haven't used so far), but I'd like to know, how a timed and networked PROGRESS can co-exist on a net. - inhibit timed from setting the clock backwards ? (sounds stupid) - run the progress server/broker from /etc/inittab (even stupider, all those broken sessions when it really happens) or is there a way (inside PROGRESS) to warn the broker and ALL clients of an pending time-change, so that all transactions are finished... *VERY* unlikely, timed would have to wait for PROGRESS to signal its OK... And onw more question: Are there other packages, which depend on time-integrity? Even PROGRESS doesn't warn about this in the installation notes. You only come across it, when you - either get the error-message - read the list of error messages in one of the many manuals..
