NOW function

PRO BASIC

The NOW function in Jspreadsheet Formulas Pro is a useful tool that provides the current date and time as a specific type of data known as a date/time value. Whenever you use this function, it automatically updates the information to the most recent date and time. This makes it highly beneficial in maintaining real-time data in your sheets. Therefore, whenever you need to track the current date and time in your Jspreadsheet, simply use the NOW function.

Documentation

Returns the current date and time as a date/time value.

Syntax

NOW()

Parameter	Description

Behavior

The NOW function is a date/time function that returns the current date and time according to the computer's system clock. Here's how it handles different scenarios:

Empty cells: The NOW function does not require any input or arguments, so empty cells do not affect its operation.
Text: Since the NOW function does not require any input, it doesn't interact with text in any way.
Booleans: The NOW function doesn't interact with boolean values, as it doesn't require any input.
Errors: The NOW function generally won't produce errors unless there's an issue with the system clock.

Common Errors

Error Name	Description
#VALUE!	This error occurs if the `NOW` function has been supplied with arguments, as it doesn't require any.

Best practices

The NOW function updates automatically whenever the spreadsheet recalculates. If you want to keep a static timestamp, you may want to use a different method, such as entering the date and time manually.

Be aware that the NOW function is dependent on your computer's system clock and will reflect any changes made to it.

If you're sharing a spreadsheet across different time zones, remember that the NOW function will display the date and time of the system where the spreadsheet is opened. This can lead to confusion if not properly accounted for.

Usage

A few examples using the NOW function.

NOW() returns the current date and time, for example: 3/15/2023 12:30:45 PM
