-# The old autowank scheme used "touch <foo> ; sleep 1"
-# to ensure differentiable, ordered timestamps. Worked, but
-# took N seconds given N files to fix. We have an example
-# which wastes multiple minutes given the old scheme.
-#
-# This version generates a sequence of timestamps
-# starting an hour ago. That gives us
-# lots to play with, in case some obnoxious program feels the need
-# to complain about timestamps in the future.

-# If we're in UTC+N land, generate UTC+(N+1)
-# If we're in UTC-N land, generate UTC-(N-1)
