Sure it can. > If you use it be sure ntpsec isn't trying to do > the same thing. It's not clear to me which NTP (protocol) packages are set up to use the util-linux stuff, assuming you're not rolling your own startup/shutdown scripts. (That's the problem in the Subject line, in a sense.) Does ntpsec have this facility built in, or are you expected to link it up to hwclock? The critical part of the whole operation AIUI is not what happens at startup, but at shutdown: writing to the RTC, and the correct preservation of its state. Cheers, David.
