I have an algorithm for a certain program. But I need help
implementing it in Excel. Here is my algorithm:

1. Take the start time (user inputted): ex. 10:03:05
2. Put it in column A, row 2
3. Add 9 seconds to start time: ex. 10:03:05 + 0:0:09 = 10:03:14
(new_time1)
4. Put new time in Column B, row 2
5. Write down "Event 1" in Column C, row 2.
6. Add 1 second to new_time1 (ex: 10:03:14): ex. 10:03:14 + 0:0:01 =
10:03:15 (new_time2)
7. Put new_time2 in column A, row 3.
8. Repeat steps 3 to 6 (incrementing new row in step 6) until end time
is reach (end time is hard coded).


Also, on step 5, I'd like to be able to change Event 1 to Event 2 for
each consecutive row.

Any tips?
TIA!
