Featured Install Changing default CentOS system timezones

In centmin.sh there's a variable called ZONEINFO which can be changed prior to Centmin Mod install to set the default CentOS system timezone. This system timezone can also be changed after install as per FAQ 8 http://centminmod.com/faq.html.

Full example of post-install timezone changes are outlined at http://centminmod.com/datetimezones.html.

---

For example for Greece, Athens you can use ZONEINFO=Europe/Athens

Code:

ls -lah /usr/share/zoneinfo/Europe/

You'd want to change your /usr/local/lib/php.ini defined timezone too date.timezone according to predefined ones at http://www.php.net//manual/en/timezones.php

 

it should set to UTC with inc/phpsededit.inc line 2 to 6 at https://github.com/centminmod/centminmod/blob/123.07beta21/inc/phpsededit.inc#L2

Code:

    if [[ "$(date +"%Z")" = 'EST' ]]; then
    sed -i "s/;date.timezone =/date.timezone = Australia\/Brisbane/g" /usr/local/lib/php.ini
    else
    sed -i "s/;date.timezone =/date.timezone = UTC/g" /usr/local/lib/php.ini
    fi

what does the command below return

Code:

echo $(date +"%Z")

 

For system timezone or PHP ?

For system pick closest city on Asia directory listing, i.e. Asia/Manila

Code:

ls /usr/share/zoneinfo/Asia/

pay attention to instructions in 1st post Install - Changing default CentOS system timezones centos 7 method is different from centos 6 method as well

to check php timezone check phpinfo page or via command line phpinfo with grep filter on timezone keyword

Code (Text):

php -i | grep timezone

Code (Text):

php -i | grep timezone
Default timezone => UTC
date.timezone => UTC => UTC

fyi, I generally use UTC time cause if you have multiple servers it easier to see what's happing at UTC time

Centmin Mod also sets a mytimes custom command which outputs various common timezones if the only reason you want to change timezone is to be able to see your timezone

Code (Text):

 mytimes
Fri Mar  2 20:27:16 UTC 2018    [UTC]
Sat Mar  3 06:27:16 AEST 2018   [Australia/Brisbane]
Fri Mar  2 12:27:16 PST 2018    [America/Los_Angeles]
Fri Mar  2 14:27:16 CST 2018    [America/Chicago]
Fri Mar  2 15:27:16 EST 2018    [America/New_York]
Fri Mar  2 15:27:16 EST 2018    [America/Montreal]
Fri Mar  2 20:27:16 GMT 2018    [Europe/London]
Fri Mar  2 21:27:16 CET 2018    [Europe/Berlin]
Sat Mar  3 03:27:16 +07 2018    [Asia/Bangkok]
Sat Mar  3 03:27:16 +07 2018    [Asia/Ho_Chi_Minh]
Sat Mar  3 03:27:16 WIB 2018    [Asia/Jakarta]
Sat Mar  3 04:27:16 +08 2018    [Asia/Kuala_Lumpur]
Sat Mar  3 04:27:16 +08 2018    [Asia/Singapore]

 

You can grep filter your initial install log in /root/centminlogs to see what was set during initial install

Code (Text):

grep -A3 'preferred localtime' "$(echo "/root/centminlogs/$(ls /root/centminlogs/ | grep _install.log)")" 

the basically finds install log name using

Code (Text):

ls /root/centminlogs/ | grep _install.log
centminmod_123.09beta01.b016_250218-032050_install.log

and does a grep -A3 for keywords 'preferred localtime' so returns matching keyword and the 3 lines after it

so example output

Code (Text):

grep -A3 'preferred localtime' "$(echo "/root/centminlogs/$(ls /root/centminlogs/ | grep _install.log)")" 
* Setting preferred localtime for VPS
*************************************************
Current date & time for the zone you selected is:
Sun Feb 25 03:22:09 UTC 2018

 

might be due to method used for centos 6 and not 7 so might need to update the routine

will update 123.09beta01 in a few moments

 

Just updated with fix

 

this can only be tested on fresh centmin mod 123.09beta01 installs

initial install time is only time the timezone is updated
