# MINSDIFF(A,B)

## DateTime Transform: MINSDIFF(A,B)

## Returns difference in minutes between Time for DateTime A and Time for DateTime B

MINSDIFF(A,B) = AbsoluteMinutes(B) - AbsoluteMinutes(A)

Where

- AbsoluteMinutes(B) = number of minutes from date reference (where date reference = Jan 0, 0000) to B

- AbsoluteMinutes(A) = number of minutes from date reference (where date reference = Jan 0, 0000) to A

## Purpose

Use this function to:

- Calculate time between events down to the minute
- Calculate the age of an event in minutes

## Return Value

| Property | Value |
| --- | --- |
| **FieldType** | Integer |
| **FieldSize** | Med / High |
| **DataType** | Discrete / Continuous |
| **DataSize** | Short / Integer |

```shell
Example Return Value: -N....N where N = maximum difference in minutes between A and B
```
