The Bot interface can be customized to display in dark theme based on Day/Night time defined. Do the following:

1. Open the chatbot.js file available in below location.

   <Installation Director >\javascripts\chatbots.js

2. Locate and edit the pre-defined variable daylight property as required.

   var dayLight ="default";
   if((new Date()).getHours()>18)
   {
       dayLight='redwood-dark';
   };

Note the following:

• Here, default is the generic theme provided by ODA based Chabot.
• The number 18 represents 6PM, and Chabot theme changes after this time has elapsed in hours. The same can be changed as required.
• Ensure not to change the variable since the same is called in the chat Widget Settings assigned to attribute theme - Widget Settings : theme: dayLight,

Once done, the daylight theme is as displayed based on time zone:
