"ping is able to calculate the round-trip time by storing the time at
which it sends the echo request in the data portion of the ICMP
message. When the reply is returned it subtracts this value from the
current time. Notice that on the sending system, bsdi, the round-trip
times are all calculated as 0 ms. This is because of the
low-resolution timer available to the program. The BSD/386 Version
0.9.4 system only provides a IO-ms timer."
