That confused me, I know that some states have weird timezones but UTC is Greenwich time.

🦆🦆🚶🏻‍♂️ says:

• Las Vegas, Nevada, United States • PDT (UTC-7)

So I checked papercall and it says

CFP closes at

• April 21, 2024 07:00 UTC
• April 21, 2024 09:00 (Local)

I'd say it means my local time, which is UTC+2 in summer in much of Western and Central Europe (CEST)

So it should rather say

• The new deadline is April 20, midnight Las Vegas time. (April 21 07:00 UTC )
