# 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)
