Syntax

DateTime.IsInNextNHours(
   dateTime as any,
   hours as number,
) as nullable logical

Description

DateTime.IsInNextNHours indicates whether the given dateTime argument (which can be of type datetime or datetimezone) occurs during the next number of hours, as determined by the current date and time on the system. This function will return false for a value within the current hour.

Examples

Let’s explore two examples to understand how the DateTime.IsInNextNHours function works.

Checking DateTime Values for the Next N Hours

Imagine you have a table with DateTime values and you want to add a column that shows true for DateTime values that fall within the next n hours. You can do this by using the DateTime.IsInNextNHours function on your [DateTime] column, where n is the number of hours you want to check.

// Output depends on [DateTime] column and n
DateTime.IsInNextNHours( [DateTime], n ) 

This expression returns true for any DateTime values in the [DateTime] column that fall within the next n hours. For example, if you set n to 2, you would use the following code:

DateTime.IsInNextNHours( [DateTime], 2 )

If the current time is 10:27:10 on July 7, 2024, this function will return true for all rows with DateTime values between 11:00:00 PM and 12:59:59 PM. Here’s a screenshot that shows how this function can be used on a DateTime table that increments by 15 minutes each row:

As the image shows, there are 8 values that fall within the next 2 hours.

Using the Current Date and Time

If you want to check with DateTime.IsInNextNHours if the current date and time falls within the next few hours, you can do that using the DateTime.FixedLocalNow function and adding a number of hours using the #duration function:

// Output: true
DateTime.IsInNextNHours(
  DateTime.FixedLocalNow() + #duration(0, 3, 0, 0), 
  3
)
