Additional Information.  I can check my video's key frame and time with the following 
command:

$ ffprobe -select_streams v -show_frames -v quiet sample.mp4 -unit | grep key_frame=1 -A 3
key_frame=1
pkt_pts=0
pkt_pts_time=0.000000 s
pkt_dts=0
--
key_frame=1
pkt_pts=500500
pkt_pts_time=8.341667 s
pkt_dts=500500
--
key_frame=1
pkt_pts=1001000
pkt_pts_time=16.683333 s
pkt_dts=1001000
--
key_frame=1
pkt_pts=1501500
pkt_pts_time=25.025000 s
pkt_dts=1501500
--
key_frame=1
pkt_pts=2002000
pkt_pts_time=33.366667 s
pkt_dts=2002000
--
key_frame=1
pkt_pts=2502500
pkt_pts_time=41.708333 s
pkt_dts=2502500
