Timezone PHP App problem with TZData

[Clovis Tristao <clovis@xxxxxxxxxxxxxx>]

Hi,

I am with problems to adjust timezone in the Squirrelmail(PHP 
Application), is appearing one hour in advance of the current schedule 
of the machine.
All the other programs are working with timezone correctly.
Some idea where I can modify to resolv this problem?

I'm using: Fedora Core 8, SquirrelMail version:* 1.4.13 / *Config file 
version: *1.4.0
*
Thanks a lot,

Clóvis
