Intelligent Trigger during specific time interval

Intelligent Trigger during specific time interval

We successfully use an intelligent trigger to have our Chat window pop up proactively if a user in on our site more than 2 minutes and this is his first visit. However we only have people responding to chats during business hours EST time. Outside business hours we would NOT like the chat to pop up automatically and prompt the visitor a chat (there is nobody to answer on our side). Is there a way to make the Intelligent trigger dependent on a time interval?
