When are design challenges due?

I know it says that the design challenges are due at 11:59pm on Feb 13, but what time zone is that in? It could make a difference if it is in Eastern time because that’s three hours less for me to work.

It’s 11:59pm Central Standard Time, or 9:59pm Pacific Standard Time.

On my computer, the time properly adjusts for time zones and shows as 9:59pm. Is it showing 11:59 on your computer?

It was, but then I logged in, and it adjusted to the settings on my account. Thanks for the answer.
