My opponent replied one day and 15 hours after I sent him a message last Thursday. He said that he could play yesterday from 4:00 PM GMT-4 onward. I arrived home and logged in Showdown and Smogon forums at 7:47 PM GMT-4 yesterday, I waited for my opponent until 8:30 PM GMT-4, unfortunately my opponent never appeared. After that, I sent him a message to see if we could play today. Eighteen hours and 20 minutes have passed and he hasn't replied. I hope he logs in today when I'm available so we can play before the deadline.
Note: My time zone is GMT-5, hence the differences in the hours of the screenshots.
