[bestrick]

I use testlink 1.8.5 version,now I found my testlink is 8 hours later than my time,so I guess the default time zone of testlink is GMT.
I tryed to change the configration here,but it does not work.Can you tell me how to localize the time displayed?Thanks!

Timezone is picked up by PHP configuration. See this post:
http://www.teamst.org/forum/viewtopic.php?f=5&t=733

That post goes to a 1.7 forum, which is now shut as 1.7 is no longer supported. Also, following the steps set out there I did not solve my timestamping issue.

Any ideas whether anything changed in 1.9 releases re timestamping? Running out of ideas now....

As stated time zone is defined in php.ini
after doing change you need to restart webserver
Of course this will have no effect on all OLD data, but will act on new write to db
