It seems quite likely that your Apple machines are getting UTC data from the NTP server, but using a local (i.e. on-the-machine) tz database for the timezone adjustment. I have the impression that Apple does not publish tzdata updates to user machines by the usual Software Update mechanism. You may need to install the latest version of tzdata, on every machine, yourself. From: tz-bounces@iana.org [mailto:tz-bounces@iana.org] On Behalf Of Michael Gardiner Sent: 03 January 2014 08:10 To: tz@iana.org Subject: [tz] Timezones in Jordan Importance: High Can you explain the current situation with regards to timezone data for Jordan. I work in the Australian Embassy in amman Jordan and am having a lot of issues with setting the correct time. On our computers when we use a NTP source such as: server 0.pool.ntp.org 120.88.46.10 server 1.pool.ntp.org server 2.pool.ntp.org server 3.pool.ntp.org It sets the clock 1 hour ahead of the correct time so I have to set them all manually which is not good. I have had a look at TZDATA2013i and it had the time as UTC +2 which should give us the correct time. Any Advise would be great.
