+# 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)
