For what it's worth, I once had this problem when pinging other hosts (not loopback.) It led me to discover that I had a bad ethernet card. tcpdump showed that I was getting corruption on return packets over the wire; since the numbering in the icmp packets was corrupted (it was actually bit shifted, leading to nice, symmetric data patterns), the timestamps which ping showed were wrong in a way similar to yours.
Since you're seeing it both to local and to foreign hosts, I would guess that the kernel may be corrupting your packets internally somehow. If other traffic is not affected, look for recent changes in ~lin/net/ipv4/icmp.c, as well as the generic ip code.
