If I am not mistaken you can use the time command

For example:

user at localhost$ time ping google.ca
PING google.ca (74.125.47.104) 56(84) bytes of data.
64 bytes from yw-in-f104.google.com (74.125.47.104): icmp_seq=1 ttl=52
time=36.7 ms
64 bytes from yw-in-f104.google.com (74.125.47.104): icmp_seq=2 ttl=52
time=36.7 ms
64 bytes from yw-in-f104.google.com (74.125.47.104): icmp_seq=3 ttl=52
time=36.5 ms
64 bytes from yw-in-f104.google.com (74.125.47.104): icmp_seq=4 ttl=52
time=36.7 ms
64 bytes from yw-in-f104.google.com (74.125.47.104): icmp_seq=5 ttl=52
time=36.6 ms
^C
--- google.ca ping statistics ---
5 packets transmitted, 5 received, 0% packet loss, time 7692ms
rtt min/avg/max/mdev = 36.501/36.659/36.747/0.153 ms

real	0m7.757s
