Web Form Builder sends emails using the UTC time zone format. Soon we'll have a feature that allows you to adjust for your local time zone, but with just a small modifiction to a php file, you can customize the scripts to send emails from your local time zone right now. Here's what you need to do:
Locate your Time Zone code.
FTP into your server and locate and edit the fbapp\php\formpage.cls.php file.
Search for "timezone".
Paste in the Time Zone code from step 1 by going to Line 127 and locating: "date_default_timezone_set( 'UTC' );". Change it to "date_default_timezone_set( 'America/New_York' );" (or whatever your code is).
Now save your changes.
NOTE: You will need to make this adjustment each time you re-upload your form if you make any changes.
