The code used native date functions, this made tests not robust.
We switch to TYPO3 API to fetch the current date and time.
Test is adjusted to define the date and time to verify code works as
expected.
Entering the continue part would end in an endless loop.
We never add anything to $i and therefore would end up here.
Existing tests ensure we don't break something.
The new test ensures we do not hit endless loop anymore.
