As I understand the Network Time Protocol (NTP), that's not necessary. Other than network proximity to the host (i.e., is it easily reached from your box?), you shouldn't need to worry where the server is located. `http://www.eecis.udel.edu/~ntp/database/FAQ/faq2Earn.htm#arang' appears to confirm that understanding: As others have pointed out, un*x systems and ntp all work in UTC (Zulu or GMT) time. The entire xntp package only uses timezone to display times in the logfile or to display to the user. ntpdate -d <server> lists the ref, orig, and xmit times in this process's timezone by using the localtime() call, and then once more at the end when it prints the syslog'ish line. It is the system library routines that get the timezone. Politeness dictates that you use a secondary NTP (stratum 2) server, unless you have a compelling reason not to. See the section entitled "Rules of Engagement" at `http://www.eecis.udel.edu/~mills/ntp/servers.html'. ----- Brian Clapper, bmc@WillsCreek.COM, http://WWW.WillsCreek.COM/ With great effort, you move the rug aside, revealing a trap door.
