rotated-pod-logs does not interact with since/since-time. This causes inspect (and must-gather) outputs to considerably increase in size, even when users attempt to filter it by using time constraints.

Suggested solution:

• parse the date from the log filename and only gather the logs when they are within the provided since or since-time flags

Acceptance criteria:

• `oc adm inspect` respects --since or --since-time flags work as expected even when used in conjunction with --rotated-pod-logs
