TYPO3 Core

Imagine this TSConfig:

admPanel {
enable.preview = 1
override.preview = 0
override.preview.simulateDate= 10
}

Setting simulateDate to a value lower than 60 seconds crashes the frontend with an unhandled runtime exception:

accessTimeStamp needs to be set to an integer value, but is empty! Maybe $GLOBALS['SIM_ACCESS_TIME'] has been overridden somewhere?

because of the following line in PreviewModule::initializeFrontendPreview():

$GLOBALS['SIM_ACCESS_TIME'] = $simTime - $simTime % 60;
