Steps to Reproduce

Follow Linkerd instructions to create issuer and cert manifest: (Official Doc)
terraform apply

Expected Behavior

No error after Terraform apply.

Actual Behavior

After changing the values as per the instructions: 24h > 24h0m0s , 1h > 1h0m0s and remove isCA: false, terraform works fine and the certs are able to be created. The cert-manager doesn't use these time format 24h0m0s but just 24h.
