I was learning about the ping command.I am not able to understand the output of ping command with -T tsonly and -T tsandaddr.The output is:$ ping -T tsonly 192.168.1.52PING 192.168.1.52 (192.168.1.52) 56(124) bytes of data.64 bytes from 192.168.1.52: icmp_req=1 ttl=63 time=0.470 ms TS:    43448298 absolute        1        31        0        -31        0$ ping -T tsandaddr 192.168.1.52PING 192.168.1.52 (192.168.1.52) 56(124) bytes of data.64 bytes from 192.168.1.52: icmp_req=1 ttl=63 time=0.434 msTS: 192.168.2.64    43461227 absolute    192.168.2.10    0    192.168.1.52    32    192.168.1.52    0I searched with google. But I didn't find the answer. In the man page also I didn't find the answer.I know the absolute time it prints is milliseconds from ut 24 hours midnight time stamp.Other than that, the remaining three times are what time? Why is that printed in both two ping outputs? What is the use of that?
-T option result in ping command
linux;ping
