ccTLD When Auctioning an .ES Domain in Auction Best Ending Spanish Time or US Time?

[Planet9]

There is a 9 hour difference between Spain & the US where I live (its 9 hours later in Spain) and my question is what time is the best time ending an .ES Auction- Spanish Time or US Time? What is the best time hour wise to end this auction- either US time or Spain time? Thank you

For a .ES domain most interested buyers will be located in Spain so focus on a convenient time for them. I would think early to late afternoon but ask the folks at Demene.
