What are the working hours of a GST Suvidha Kendra?

As you already know it’s a Sole proprietorship type of business, there is no time limit, and holiday rules are predefined. But yet most of the GST Suvidha Kendra businesses are open from 9:30 to 6:30 pm. So before going to any GST Suvidha Kendra ask on a phone call about their working hours.
