有時當我們裝Ubuntu系統時,沒有設定好時區,導致Log的時間記錄不正確,可以事後進行時區及時間的校正,做法如下

#? 43 這裡按43選Taiwan

The following information has been given:

Taiwan

Therefore TZ='Asia/Taipei' will be used.
Local time is now: Mon Apr 20 20:39:28 CST 2015.
Universal Time is now: Mon Apr 20 12:39:28 UTC 2015.
Is the above information OK?
1) Yes
2) No
#? 1 這裡按1確認剛剛的選擇

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

# cp /usr/share/zoneinfo/Asia/Taipei /etc/localtime

# ntpdate time.stdtime.gov.tw
20 Apr 20:40:21 ntpdate[9271]: adjust time server 118.163.81.61 offset -0.016625 sec

# date
Mon Apr 20 20:43:51 CST 2015

好了,這樣我們就把時間設定回+8 Taipei了.
