You can change the timezone for your account or for a specific folder by adding this rule to your .htaccess file:
SetEnv TZ Timezone
For example, if you wish to change the timezone to America/New_York, you should add this line to your .htaccess file:
SetEnv TZ America/New_York
This way your scripts will use your local time instead of the server time.
A full list of the available timezones can be found at this URL.
Alternatively, you can use the PHP Variables Manager tool to set the date.timezone PHP variable to the one you need.
