9. An electronic watch at 9:15:12 AM shows the time as $09: 15: 12$, and at 1:11:29 PM, it shows the time as 13:11:29. Then, within 24 hours a day, the number of times the six digits on the electronic watch form a symmetrical time (i.e., reading from left to right is the same as reading from right to left, such as 01:33:10) is $\qquad$ .
【Answer】 96
【Analysis】Let $\overline{a b}: \overline{c c}: \overline{b a}$,
$c$ can take 0 to 5, a total of 6 possibilities.
$\overline{a b}$ can take $00,01,02,03,04,05,10,11,12,13,14,15,20,21,22,23$ for a total of 16 cases.
Therefore, there are $6 \times 16=96$ in total.
