How do you set time zones in Apache Virtual Hosts?

Virtual hosts and Time Zones

[TheGreen]

i.e. vhost 1 is CST, vhost 2 is EST.

Does any one have a bookmark or a how to? I am using PHP so perhaps there is a way to set a php.ini file for each virtual host? I have been searching, but havent found anything really clear yet. Thanks.

Have you tried Setenv TZ EST in the VirtualHost section?
(Maybe setenv TZ "US/Eastern" is better ...)
