# 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)
