"on the Japanese city of Hiroshima"

"at 8:15 a.m. local time"
Verified
The 8:15 AM local time is confirmed by Britannica, the Truman Library, the U.S. National Archives, and the Atomic Archive. Minor variance exists in some Japanese contemporary logs (recording 8:16, 8:20, or 8:30), but 8:15 AM is the universally accepted and officially commemorated time, including at Hiroshima's own Peace Memorial Museum.

Origin trace: Some original Japanese contemporaneous reports cited 8:16, 8:20, or 8:30; the 8:15 figure was established from U.S. military records, particularly Manhattan Project director Leslie Groves' account, and has been adopted as the official time.
