Each time TYPO3 renders a content element, it stores its timestamp value in SYS_LASTCHANGED in the REGISTER, keeping it warm until the end of the page rendering process
-> in \TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer::lastChanged

and then saving then value in the DB.
-> in \TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController::setSysLastChanged

If you use RESTORE_REGISTER cObject in your TS, it will reset the Register, setting it back to the previous values
-> in \TYPO3\CMS\Frontend\ContentObject\RestoreRegisterContentObject::render

So if RESTORE_REGISTER is used in a TYPOSCRIPT, the registered SYS_LASTCHANGED value is reset before being stored in the DB, so SYS_LASTCHANGED updates are may never be saved in DB.

SYS_LASTCHANGED temp value should not be set in Register in order to avoid it being reset.

This bug also exists in TYPO3 9.5.13.

There is a problem with the Introduction Package because the "bootstrap_package" extension uses "RESTORE_REGISTER" in lib.dynamicContent.

It concerns the TypoScriptFrontendController class.

The problem still exists in TYPO3 v10.

If any RESTORE_REGISTER is called, the temp value for SYS_LASTCHANGED is gone. Since ext:fluid_styled_content suggests using RESTORE_REGISTER for inserting content in the page template based on FLUIDTEMPLATE (see lib.dynamicContent), a lot of site-package extensions make use of it (like the bootstrap package). So in many TYPO3 installations SYS_LASTCHANGED is only updated for changes of the page properties but not the page content. This might be a problem, since the ContentObjectRenderer.php reads "The SYS_LASTCHANGED timestamp can be used by various caching/indexing applications to determine if the page has new content." - which will not work as intended then. Also, some sites use SYS_LASTCHANGED to show a "Last Updated on ...", even though it is not intended for that originally - this also fails with the value not being written correctly.

If 'SYS_LASTCHANGED' is stored outside the $register variable, it's no longer available via 'data = register:SYS_LASTCHANGED' in TypoScript.

Quick solution:

public function render($conf = []) {
$SYS_LASTCHANGED = isset($GLOBALS['TSFE']->register['SYS_LASTCHANGED']) ? $GLOBALS['TSFE']->register['SYS_LASTCHANGED'] : false;
$GLOBALS['TSFE']->register = array_pop($GLOBALS['TSFE']->registerStack);
if($SYS_LASTCHANGED !== false)
return '';

So 'SYS_LASTCHANGED' is still available in register but is not restored when RESTORE_REGISTER is called.

We have the same problem. Especially with indexed_search which does not recognize changes to the page content.

Quickfix successfully tested under 10.4
