And what exactly the "time" is? As I see in the script, is it in ticks? means the time instance, or the inter-arrival time?
"time" is a packet arrival timestamp, in microseconds, relative to the time the receiver is started. It is calculated by counting received samples so it based off a clock in the USRP, not a clock in the PC. By comparing the timestamps of two received packets you should be able to determine difference in actual arrival times to with a couple microseconds.
