When i send a packet the last think i put into the packet is the local time that it was sent. For this i am using chrono, but the problem is that it returns a INT64 which isn't supported. If I cast the data into a different type it just isn't precise enough! I cant use sf clock as I need to use the local time so i can measure the Round Trip time of the packet. So has any one had this problem and how did they get around it ?
