The NYTimes is organizing this planet-wide “moment in time” event when photographers all over the world take a snapshot at exactly 15:00 UTC (or GMT), thus forever capturing that single moment in the life of our planet. You then have 5 days to upload it to their website for all to view.
15:00 UTC is Sun 11:00 AM in Toronto, Sun 8:00 AM in Vancouver. Find the time in your country and time zone.
