Important: #92736 - Return timestamp as integer in DateTimeAspect 

See forge#92736

Description 

The DateTimeAspect, introduced to supersede the use of superglobals like $GLOBALS['EXEC_TIME'], can be used to retrieve the current timestamp.

$context = GeneralUtility::makeInstance(Context::class);

// Used instead of $GLOBALS['EXEC_TIME']
$currentTimestamp = $context->getPropertyFromAspect('date', 'timestamp');
Copied!

This timestamp is now correctly returned as int instead of string.

Therefore, extension authors should check if they currently rely on receiving the timestamp as string and if so, adjust the consuming code accordingly.
