Timestamp for Chats in Zoho Desk

Timestamp for Chats in Zoho Desk

I am trying to assess the volume of chats we receive and at what times through the chat feature in Zoho Desk. Unfortunately I cannot seem to get a report that pulls the accurate time that the chat occurred/ was submitted. I was trying to get the information through the "ticket created" times, and due to the variation in the time delay between the time that the chat can be concluded and when it gets converted into a ticket, it was not possible to accurately know the time that the chat actually occurred.  Any suggestions on how I can find that information in Zoho desk, or how to get a report to pull that information for me?
