TYPO3 Core

I confirm, that this is still (or again) an issue in version 9.5.17

Same in 9.5.18

I found that the PreviewSimulator middleware clear the DateTimeContext set by the admin panel's PreviewModule middleware.

Disabling the PreviewSimulator middleware fix the issue for my use case.

I can confirm it for TYPO3 v9.5.19.

This patch solves the display of the timed content elements
https://review.typo3.org/c/Packages/TYPO3.CMS/+/64491

but it does still not show the "Preview" box on the site (which i suspect is the expected behavior if i look at the code.)

So i had not only to delete the `$GLOBALS['TSFE']->clear_preview();` call, but also add

if ($queryTime === false && $GLOBALS['SIM_ACCESS_TIME'] !== $GLOBALS['ACCESS_TIME']) {
    $queryTime = $GLOBALS['SIM_ACCESS_TIME'];
}

to the `simulateDate` method because ADMCMD_simTime is not filled when setting the simulation time using the admin panel.

see:
https://github.com/lsascha/TYPO3.CMS/commit/59c23fd2d43e2676e8fa8eb69f40ef9a69f399c8

we could confirm the bug and the proposed bugfix
