ntpdate and Israel local time
Hello, On my desktop at home, when I want to to update the local time (I live in israel) I run: ntpdate -s ntpserver.huji.ac.il And it work OK. However, there is a server at my work place which I am responsible for. When I run: ntpdate -s ntpserver.huji.ac.il it sets the time to 7 hours earlier (I mean, instead 19:00, it is 12:00). I assume this has something to do with Time zones, but this machine has no X windows installed at all so I don't have a GUI for setting time zones. What causes this error ? What should I do ? any advice ? rgs, DS ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

'date' will show you the time including the timezone. for example: $ date Thu May 27 21:47:50 IDT 2010 (IDT = Israel Daylight-savings Time) If your timezone is wrong, you can: cp /usr/share/zoneinfo/Israel /etc/localtime And then try date again. the time will probably change, and you'll need to re-set it with 'date' to the correct time: date MonthDayHourMinute Of course you could simply sync your synchronization server with an accurate time which makes the most sense: an Internet NTP server, or in the lack of Internet access, something independent (i.e. a GPS receiver...)

In Debian/Ubuntu you can use: $ tzselect Then when you got that set up run (as root): $ ntpdate-debian On 5/27/10, Oron Peled o...@actcom.co.il wrote: On Thursday, 27 בMay 2010 21:50:12 geoffrey mendelson wrote: On May 27, 2010, at 9:37 PM, Dan Shimshoni wrote: ...

In fact, that's what he was doing. His issue is that ntp synchs the machine's clock with UTC. So in fact his internal clock is already correct. All he needs to do is set the proper time zone, as you said yourself. Herouth ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
