timecop was added as spec dependency in Facter for a specific AWS-related test: https://github.com/puppetlabs/facter/commit/8c323415a59025232fc06e1dc5853e10c5ee8a32
However, we've recently run into an issue while testing Ruby 3.2.0 preview releases because of how timecop interacts with Psych: https://github.com/travisjeffery/timecop/issues/390
We should deprecate timecop from the AWS test to reduce our external dependencies.
