meaning
Since Steve Jobs introduced Apple in 2007, he began to adjust the time to 9: 4 1, and gradually continued this practice, so the release time of an Apple mobile phone was changed to 9:4 1 every time, and it has not changed until now.
The person concerned said that it was because Jobs found in his speech that the relevant contents of the slides were played at different times. Under his careful calculation, the picture of Apple mobile phone appeared at 9:4 1, so he asked all Apple mobile phones to appear at this time from now on.
