Let's say you are located in Taiwan how do you change time zone to that of Taiwan?
I am using Nginx 1.4.1. My default time zone is UTC+0 or GMT+0. My OS is Ubuntu 10.04.4 LTS.
Find the time zone text
Many know they need to indicate the desired time zone in Nginx's configuration file, but they may not know how to find the correct text that reflects the timezone Nginx would understand. It's unbelievable that not many on Google know the answer; so I've decided to walk you through exactly how to find your timezone.
Use Unix command tzselect and follow the prompt to find the text that represents the desired time zone.
If you are looking for a list of valid time zones look no further. Simply use the Linux command tzselect to pinpoint the time zone you need.
Suppose you are looking for Taiwan's timezone here's the trace of running the command tzselect on my Ubuntu box.
$ tzselect Please identify a location so that time zone rules can be set correctly. Please select a continent or ocean. 1) Africa 2) Americas 3) Antarctica 4) Arctic Ocean 5) Asia 6) Atlantic Ocean 7) Australia 8) Europe 9) Indian Ocean 10) Pacific Ocean 11) none - I want to specify the time zone using the Posix TZ format. #? 5 Please select a country. 1) Afghanistan 18) Israel 35) Palestine 2) Armenia 19) Japan 36) Philippines 3) Azerbaijan 20) Jordan 37) Qatar 4) Bahrain 21) Kazakhstan 38) Russia 5) Bangladesh 22) Korea (North) 39) Saudi Arabia 6) Bhutan 23) Korea (South) 40) Singapore 7) Brunei 24) Kuwait 41) Sri Lanka 8) Cambodia 25) Kyrgyzstan 42) Syria 9) China 26) Laos 43) Taiwan 10) Cyprus 27) Lebanon 44) Tajikistan 11) East Timor 28) Macau 45) Thailand 12) Georgia 29) Malaysia 46) Turkmenistan 13) Hong Kong 30) Mongolia 47) United Arab Emirates 14) India 31) Myanmar (Burma) 48) Uzbekistan 15) Indonesia 32) Nepal 49) Vietnam 16) Iran 33) Oman 50) Yemen 17) Iraq 34) Pakistan #? 43 The following information has been given: Taiwan Therefore TZ='Asia/Taipei' will be used. Local time is now: Sun Jun 9 14:36:42 CST 2013. Universal Time is now: Sun Jun 9 06:36:42 UTC 2013. Is the above information OK? 1) Yes 2) No #? 1 You can make this change permanent for yourself by appending the line TZ='Asia/Taipei'; export TZ to the file '.profile' in your home directory; then log out and log in again. Here is that TZ value again, this time on standard output so that you can use the /usr/bin/tzselect command in shell scripts: Asia/Taipei $As you can see the valid time zone string is Asia/Taipei. In the following step we'll be using this value.
Edit Nginx startup script
Edit Nginx startup script which is usually /etc/init.d/nginx. Mine looks like the following.
#! /bin/sh ### BEGIN INIT INFO # Provides: nginx # Required-Start: $local_fs $remote_fs $network $syslog # Required-Stop: $local_fs $remote_fs $network $syslog # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: starts the nginx web server # Description: starts nginx using start-stop-daemon ### END INIT INFO export TZ="Asia/Taipei" PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/local/nginx/sbin:/usr/sbin:/usr/bin DAEMON=/usr/sbin/nginx NAME=nginx DESC=nginx ...As you can see I added export TZ="Asia/Taipei" at the very top. That's all you need for Nginx to understand that you would like to use the indicated time zone in log entries.
Restart Nginx. In my case the Unix command is sudo /etc/init.d/nginx restart. Once you reboot Nginx server you'll see that the web log is using the desired time zone as the following snippet shows.

Easy when you know exactly what to do isn't it?
