It's not exactly what you were looking for, but if you can access and external ssh server, you can run it through that, and the results will reflect the ping time to the ssh server:

$ ssh username@server 'ping -c 1 google.com' 
PING google.com (72.14.204.147) 56(84) bytes of data.
64 bytes from iad04s01-in-f147.1e100.net (72.14.204.147): icmp_seq=1 ttl=57 time=2.64 ms

--- google.com ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 2.640/2.640/2.640/0.000 ms
