It's impossible to create cron jobs for exactly midnight

[siovene]

Hi,
the following command fails with error: must specify at least one schedule:

hyper cron create --hour=0 --minute=0 --name my-cron-job my/image do_something

However, if I change the hours and minutes to something other than 0, the job is registered successfully.

Platform: macOs High Sierra 10.13.2
hypercli: 1.10.16, build 860cca2
