cache_clearAtMidnight wrong calculation of midnight
0%
Description
In typo3 > sysext > frontend > Classes > Controller > TypoScriptFrontendController.php function get_cache_timeout() midnight is calculated by adding $cacheTimeout.
Line 4461:
$timeOutTime = $GLOBALS['EXEC_TIME'] + $cacheTimeout;If config.cache_period > 86400 then midnight is far in the future. Cache for page with UID = 20 will clear at midnight in 7 days.
Example:
config.cache_period = 604800.
[globalVar = TSFE:id = 20]
config.cache_clearAtMidnight = 1
[GLOBAL]
Possible solution in line 4461:
$timeOutTime = $GLOBALS['EXEC_TIME'] + 86400;

Seems I run into this issue in one of my projects (TYPO3 8.7.8).
When I understand this correct, using
config.cache_period = 86400
in addition to cache_clearAtMidnight should be a working temp fix, right?

config.cache_period = 86400
is default value in TYPO3 7.6 LTS. Maybe in TYPO3 8.7 LTS too. If you don't change this value you can use
config.cache_clearAtMidnight = 1
without errors. For further discuss switch to stackoverflow.

This basically works as advertised, see https://docs.typo3.org/m/typo3/reference-typoscript/master/en-us/Setup/Config/Index.html#cache-clearatmidnight
"With this setting the cache always expires at midnight of the day, the page is scheduled to expire." -> so it should not expire at the next possible midnight, but exactly like it does: midnight on the day the page would expire (idea is to avoid clearing cache during main business hours).
