Localtime problem and weather update in xfce (solved)

Hi.
I set localtime with this commands:

ln -s /usr/share/zoneinfo/Asia/Tehran> /etc/localtime

and then:

hwclock --systohc --utc

But in xfce weather plugin the clock not show correct.
Here is the pictures of xfce weather plugin.

http://www.zimagez.com/full/02e720e8ebb … b93641.php

In the pictures the time of weather plugin is 15:30. But my system time is 11:00. The correct time is 11:00.
How can i solve this?
Thanks and sorry for my bad english!

I think what's happening is that the weather plugin is getting a timestamp from the weather service it's connecting to, but your system clock is off. It can happen changing to UTC. My suggestion is to go to Xfce's date and time settings and look for an option to update ntp. It must be there somewhere.

I go to date and time settings. And i see the timezone is not set(empty).
When i put localtime to my location(Asia/Tehran) The system time is changed to 15:50!
And now the system time and weather time is the same. But it's not correct. The correct time in tehran now is 11:23!

Do you have ntp installed? If you're not sure, run

pacman -Qs ntp

That means you don't have it. Installing it might help, and then try running

ntpd -q

Re: Localtime problem and weather update in xfce (solved)

... the time of weather plugin is 15:30. But my system time is 11:00. The correct time is 11:00.

What do you mean the system time is 11:00?  How do you determine this?  Show the commands you used, and the output they produce?

What do you mean the "correct" time is 11:00?  Is this what a clock on your wall shows?  If that  is the case, that is *not* the correct UTC time, that is the local time.  For an Iranian timezone (and assuming a summer time adjustment) everything is working as expected: the local time displayed by your system should be 4.5 hours ahead of the UTC time set in the hardware clock.

This has been covered ad nauseum on these forums and in the wiki: https://wiki.archlinux.org/index.php/Time

Re: Localtime problem and weather update in xfce (solved)

Hi.
I set localtime with this commands:

ln -s /usr/share/zoneinfo/Asia/Tehran> /etc/localtime

Is this a typo?

# ln -s /usr/share/zoneinfo/Asia/Tehran /etc/localtime

What is the output of:

ls -l /etc/localtime
timedatectl

Are you infected with Wetiko?

Here is the output:

Re: Localtime problem and weather update in xfce (solved)

Where's the other output he asked for (which also addresses my questions)?

EDIT: I read to quickly - your timezone isn't even set properly.  The typo was not just when you entered it on the forums, but was when you tried to set it.

I suspect you'll need to reinstall [core]/tzdata to fix the damage you've done, then follow the wiki page I've linked to.  Once you've done that, if there are still problems, come back here and provided the diagnostic information we've asked for (timedatectl).

EDIT 2: something is really fishy here.  That link goes to UTC, which would cause one set of problems.  But the times you provided in your initial post suggest your system is working properly on Iran summer time.  So please do post timedatectl so we can stop guessing and actually see what is happening.
