Get the current date and time (serial value).
This function is often used as an automatic entry for document creation time, etc.
How it works
=Now()
Example Results
When a file is reopened or a cell (even a cell without a NOW function) is recalculated, the result changes.
Therefore, when the date is actually entered, it must be converted to a fixed value by pasting a value in order for the date and time to be fixed.
