The quote doesn't say that anyone beside Allah has the knowledge of the Hour or that anyone has the complete knowledge of the Five.
Beside that the quote says that knowledge of the Five is required for ahl al-tasarruf to wield their authority. If we assume that the quote is referring to complete knowledge of the Five, including the exact time of the Hour, then we also have to accept that none of the major awliya' were from 'ahl al-tasarruf' as they denied this knowledge for anyone beside Allah.
Some of those include:
Shaykh Makki bin Abi Talib al-Maliki
Shaykh Abu ‘l-Qasim ‘Abd al-Karim al-Qushayri
Shaykh ‘Abd al-Qadir Jaylani
Muhyi al-Din ibn ‘Arabi
Shaykh Sa’di Shirazi
Shaykh Sahl bin ‘Abdullah al-Tustari
Shaykh Ibn ‘Ajibah
Shaykh Isma’il Haqqi Bursawi
Tawil is required either way.
