Trending @Cognizant; RTO for Bench Queries!

As per the last communication, we’ve to come to office for 5 days and maintain 6-8hrs! So I’ve below queries!

1. Can we report to any other location than base location? If yes, is there any approval we need to have.
2. If I apply wfh top-up for 10hrs when I don’t go to office and my bench manager approves it, still I’ve to visit the office?
3. I’m guessing the first in of the day and last out gets count. So if I’m punch in the morning, came back home and go to punch out at night, will that work?

Thank you in advance.
