How to use VCR even if your tests depend on Date.today/Time.now, +/- 100 days/seconds.
VCR.configure do |config|
config.cassette_library_dir = "spec/cassettes"
config.hook_into :faraday
# If a test uses a value that depends on the current time, then the recording
# become stale as time marches on.
# This setting will replace specific "absolute time" values with time-relative
# keywords when the recording is first made.
# On subsequent replayes, the time-relative keywords are substituted with
# the appropriate value, so the value is relative tot he current time.
