>From: Unidata User Support <address@hidden> >Organization: Unidata Program Center/UCAR >Keywords: LDM IDD clock skew David, et. al., We have noticed that all sites receiving the NLDN feed from striker2 are showing a latency pattern that varies between 0 and 30 seconds over a 6 hour period. Here are three examples: University of Northern Florida: http://my.unidata.ucar.edu/cgi-bin/rtstats/iddstats_nc?NLDN+crusty.cocse.unf.edu University of Oklahoma: http://my.unidata.ucar.edu/cgi-bin/rtstats/iddstats_nc?NLDN+stokes.metr.ou.edu Unidata: http://my.unidata.ucar.edu/cgi-bin/rtstats/iddstats_nc?NLDN+shemp.unidata.ucar.edu The pattern looks like striker2's clock is drifting by 30 seconds over a 6 hour period and then being reset. I, for one, am baffled by this behavior since I am under the impression that striker2 is a Sun Solaris SPARC box, and Suns typically have much better clocks than that (PCs, on the other hand have incredibly bad clocks). If the time on striker2 is not being set by ntpd, would you consider changing the configuration so that it is? Thanks in advance for your consideration. Cheers, Tom
