Неверная отметка времени в системном журнале

Я посмотрел на свой системный журнал, и я нашел это:

Nov 30 22:30:01 nori-hidamari NetworkManager[963]: <info> (wlan0): canceled DHCP transaction, DHCP client pid 2580

Так что, похоже, одна временная метка странна. Должен ли я беспокоиться об этом?

Спасибо, ребята, что помогли мне.
