When using the Gradient Works Book It Live capability you will want to manage your users working hours within the Gradient Works Queue. This allows flexibility based on where your users are located and/or allows users to adjust for their customer's time zone.
There are two things thats that Gradient Works will take into consideration when scheduling a time for Book It Live:
1) The working hours in the Gradient Works Queue
2) Free and busy time slots in the user's calendar (Gmail/Outlook)
If the working hours in the Gradient Works Queue is blank, the only consideration will be the free/busy slot in the user's calendar
Important Note: The Gradient Works Working Hours is based on your Salesforce environment's time zone. Example: If your system is in the Central Time Zone, please make the necessary calculations for user's in other time zones.
Setting Working Hours
Launch your Gradient Works app and click on the Queues tab within the application
This will take you to the list of Queues that you have created. From here you can manage your the users in the respective Queues and set their working hours. In the below screenshot, you would click on "Lily Youn" and it will take you to the page where you can set the availability.
From here, you'll be able to set working hours for this particular user. Please note, if you are setting working hours for a user that does not reside in the same time zone as your Salesforce environment's time zone you will need to make the necessary calculations to match the user's working hours.
Ex. Your Salesforce Environment is in Central Time Zone but you have an user that lives in the Pacific Time Zone. Your normal working hours are from 9:00am - 5:00pm.
To set the proper hours for the Pacific Time Zone user, you'll want to input 11:00am - 7:00pm in the Gradient Works Working Hours Start/End.
