5080/5090 Release time and purchasing

Hi all,

I know that the scheduled release date for the new 5000 series gpus is January 30th. I was wondering, does anyone know the exact time they become available? I'm specifically looking to snipe one on Amazon before they sellout. I'm trying to figure out the time, so I can sit at my desk and refresh the page at the proper time 😄. Thank you in advance for any help, and have a great day.
