Invites Acceptance Delay
The date and time in the chat of a new contact is the date and time when the new contact accepted your connection request.
When you send a connection request via CompLeadly, the date the request was sent is recorded. Let's say you sent the request on July 1st. If the contact accepts this request on August 1st, August 1st will also be displayed in the chat, not July 1st.
To see the exact date of the original invite, you can use the CompLeadly feature "Contacts". There, the respective date is displayed in the column "last visited Invite". This way, you always keep track of your connection requests and can trace when they were sent.
