It sure is something that scientists can get the time and placement of the picture to such an exacting degree. They said:
Using lunar tables, topographic maps, weather records and astronomical software, backed by a scouting trip to Glacier Point itself, the researchers believe that Adams pressed the shutter on September 15, 1948 at 7:03 p.m. Pacific Daylight Time.
They could even discern the location where he took the picture:
By comparing the colour version with the black-and-white one, Olson was able to determine that Adams set up his tripod just off the Yosemite Park trail, below a geology hut. They believe their calculations are accurate to within 10 feet (three metres).
This would be an interesting thing to do with other famous photos as well.
