Its the time of the person who banned you so if like someone bans you and they live somewhere else like say you live in the USA and they live in England the time and date is different so once in I live in the USA and somewhere where its one more day from where I live and they ban me then if I get un-banned on the 7th and I got banned on the 5th I'm actually getting un-banned on the 6th because its a different date/time over there.
