Hello Alksanya, 6.2.10 Auction holders (sellers) must sell to the highest bidder with a valid bid at the end of the auction or to the first buyer to accept a valid Buy-It-Now ("BIN") price before the auction ends. Rule 6.1.17 applies.
End Time - This must be clear with an hour, minute and time zone or X hours after last bid. (Default 72 hours after last bid)
You can not designate when your auction will end outside of the rules above.
Please edit your post to comply.
