Just saw this on the NYT web site:

They want photos from around the world all taken exactly at 15:00 UTC on 2 May. You've got 5 days to get them the file, so this would be a challenge for LF shooters, but not insurmountable. That's 8AM on a Sunday for California, so this appears to be more appropriate for more eastern time zones.

I didn't see any link to their copyright policy, hopefully it's not too onerous.
