Good catch. We're using roaming profiles here, so my home dir is on some
network drive. If I re-run the test on a local disc, I get the
following:

$ ~/workspace/emacs-bug/20140731clockskew/clockskewtest.sh

That is, no time difference. But why does the network drive affect only
emacs and not touch?
