Linux – CentOS Ignoring Timezone and showing UTC

centoslinux

I've set my server's timezone to Central:

/etc/localtime -> /usr/share/zoneinfo/US/Central

After rebooting, when I run the date command, the time is still listed in UTC.

[root@dev etc]# date
Sat Oct  5 16:14:28 UTC 2013

How can I get it to display in the local timezone?

You could check if there is something wrong with this file: /etc/localtime

Using for example:

zdump -v /usr/share/zoneinfo/US/Central or zdump -v /etc/localtime

In my case the information for this year looks like this:

/usr/share/zoneinfo/US/Central  Sun Mar 10 07:59:59 2013 UTC = Sun Mar 10 01:59:59 2013 CST isdst=0 gmtoff=-21600
/usr/share/zoneinfo/US/Central  Sun Mar 10 08:00:00 2013 UTC = Sun Mar 10 03:00:00 2013 CDT isdst=1 gmtoff=-18000
/usr/share/zoneinfo/US/Central  Sun Nov  3 06:59:59 2013 UTC = Sun Nov  3 01:59:59 2013 CDT isdst=1 gmtoff=-18000
/usr/share/zoneinfo/US/Central  Sun Nov  3 07:00:00 2013 UTC = Sun Nov  3 01:00:00 2013 CST isdst=0 gmtoff=-21600

You can also do :

dpkg-reconfigure tzdata

It will then allow you to choose your timezone.

This is because your system is set to use UTC (or has no Time Zone set) and not JST. The date command will accept JST as an input modifier but then uses the system default to display it. If you want your system to want your system to display the time in JST format then you should set the timezone to JST

remove or rename /etc/localtime and then link the relevant file in /usr/share/zoneinfo to /etc/localtime

cd /etc
mv localtime localtime.orig
ln -s /usr/share/zoneinfo/Japan /etc/localtime

Edit

To answer your comment - The date command has to be able to understand time zone information provided as part of the date string parameter of -s and what to do with it. If you examine the source code you will find that all of the common time zone abbreviations, and their offsets from GMT are defined. This information is then used to set the time correctly. Depending on the version of core-utils you examine you'll find the information in lib/parse-datetime.c or lib/getdate.c
