No, your frame rate is obviously 23.976, or it's most likely INcorrrectly 24.
The first frame of the comp is frame ZERO, as in 00:00. The last frame is 09:23. Which is what you set it to be.
00:00 - 09:23 is ten seconds. 00:00 - 10:00 is ten seconds and one frame. If the beginning frame was frame ONE, you'd be correct in your statement of woe. but the beginning frame is frame ZERO.
Thank you for the explanation, makes sense. I just needed to understand.
You could use the page down key or Ctrl/Cmnd + Right Arrow to move to the frame at 10:00 but there would be nothing there because the last frame of the comp starts 1 frame duration before the end of the comp and ends at the end of the comp. Sometimes it's hard to visualize time.
