This is a hacky POC; we need to implement rootless PCM in the proper way.
Especially, pcm.Exists(existingPodName) needs to be implemented to return true
even when cgroups is not available.

This change handles the case where the ith cronjob may have its start
time set to nil.

would panic when calling Before on a nil StartTime.
