Dst 2007

[bigdessert]

I heard about the new Daylight Savings Time going into effect this year. Is there an update for whm/cpanel that will update to the new DST dates? Also does a patch need to be applied to the OS to reflect the new DST dates? I am worried that when the day comes all of our email will be off because the server time is off...

You will just need to download a patch for your operating system (if you haven't already done so already) that will account for the new daylight savings time start and end dates.

Hi,

I'm also facing the same issue. Please let me know the fix for this DST lag issue for linux OS..

[ujr]

centos users, can see this: http://www.centos.org/modules/newbb/...=6802&forum=27

Does anyone know if a reboot is required after updating the time zones?

[jackal]

How about freebsd and Fedora?

[ujr]

should be more or less the same.

when you run the following, does it give you the correct dates?

/usr/sbin/zdump -v /etc/localtime | grep 2007

It should show you Mar 11 and Nov 4th of 2007 for the changes

you shouldn't have to.

[ujr]

Also, please note that it seems to be in the most recent yum updates, so your system may already be updated. Check it by running the command above (2 posts up)

Thanks most are, got some work left to do though.

For those running Red Hat (or CentOS this applies).

In short, so long as your running at least tzdata-2005m-1, your safe.

Also do the command mentioned by ujr to verify that the current /etc/localtime has been updated from the updated tzdata files. If it hasn't, run /usr/sbin/tzdata-update or do the suggested commands mentioned in the above URL.

It amazes me why some hosting company's run their servers on local time. Unless all your clients live in your local town, it surely makes sense to run on UTC/GMT ( which never changes )

[ujr]

agreed kernow, but nevertheless, the tzdata needs to be updated for the system to calculate the proper times in all timezones, if you rely on system time.

If it displays the following, is this the correct TZ?

root@destiny [~]# /usr/sbin/zdump -v /etc/localtime | grep 2007
