Pi Time 03/14 1:59:26.535... UTC as shown on a SyncServer S200 Stratum 1 NTP clock with a Rubidium (Rb) atomic frequency source that was time stamped against 11 GPS satellites.
This image was taken with a Canon EOS 1D Mark III camera shooting at a burst rate of 6.25 fps. The exposure times were 1/60 of a second. The burst was synced against the clock with such that this image was taken 0.525 seconds +/- 0.004 seconds (interval at 2 standard deviations) after the 1:59:26 UTC. The earliest interval for that image is [1:59:26.521, 1:59:26.538] UTC and the latest interval is [1:59:26.529, 1:59:26.546] UTC. Therefore this photo recorded light from the atomic clock at Pi time (03/14 1:59:26.535... UTC) to an accuracy of about 2 standard deviations.
