TYPO3 Core

TYPO3 page cache ignores start and end time for content and pages. This causes problems related to caching:
- if a content element has start time set, it will not be shown at that time until the page expires
- if a content element has end time set, it will be shown after that time until the page expires
- If a page has start time set, it will not be shown at the right time in menu on cached pages until cache for those pages expires
- If a page has end time set, it will be shown in menu on cached pages after the end time causing 404 errors until cache for those pages expires
