I downloaded all the updated image markup files from the server, validated them, and loaded them into the db. Everything seems to be fine.
Greg and I also checked the time on the Chicory computer, and it seems to be right (within five minutes). It gets its time from the DNS servers on the network, so if it were wrong, every other machine in the UVic domain would probably be wrong too. If it happens again, let us know right away and we'll check it out.
