Dear researcher: Thanks for your job first. It's a great job for me to learn about ADS-B. After I read the guide book, I find all the time stamp seems like a local time. So I want to know whether ADS-B broadcast it's own clock in ADS-B frame. If so, how can I capture it.

ADS-B does not broadcast any time information. You have to rely on the receiver clock. Some ADS-B receiver can connect to a GPS receiver to provide an accurate timestamp.
