Hi, I want to add the actual date in cell A1 when B1 is populated for the
first time, A2 when B2 etc...
I have tried the formula =today(), but the result is recalculated everytime
the spreedsheet is opened. I have also tried to turn off auto-calculation,
but I need the calculation on new entries. When I calculate manually, every
cell is updated.

I have tried to create a macro that fill the cell as a date instead of a
formula (the command ctrl+shift+ and that works, but I would like this to
happen automatically when the user enter, exit or pick a value in cell.
Does anyone have any suggestions on how to make this happen?
