# To Unix timestamp

## Description

This operation converts a date and time into a Unix timestamp. A Unix timestamp is the number of seconds (or milliseconds) that have elapsed since January 1, 1970, 00:00:00 UTC (commonly referred to as the "Epoch").

## Data types

These are the input/output expected data types for this operation:

### Input data

![](https://965373739-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FkxZeV4nlXcIAjMGZxzLI%2Fuploads%2F19RZEXRonymaymkWujGR%2Fimage.png?alt=media\&token=31a8bb81-bfd0-4011-bbdf-f7933a84b11d) - Strings representing the dates you want to transform. Permitted date formats are the ones allowed by the Go time package. [Check this article](https://go.dev/src/time/format.go) to see all the valid formats.

### Output data

## Parameters

These are the parameters you need to configure to use this operation (mandatory parameters are marked with a <mark style="color:red;">**\***</mark>):

<details>

<summary>Unit<mark style="color:red;"><strong>*</strong></mark></summary>

Specify the unit of time of the output timestamp. Choose one of the following:

* **Seconds**
* **Milliseconds**
* **Microseconds**
* **Nanoseconds**

</details>

***

## Example

Suppose you want to convert a series of **dates** into **Unix timestamps**:

1. In your Pipeline, open the required [Action](https://onum.gitbook.io/onum-docs/the-workspace/pipelines/actions) configuration and select the input **Field**.
2. In the **Operation** field, choose **To Unix Timestamp**.
3. Set **Time Unit** to **Seconds**.
4. Give your **Output field** a name and click **Save**. The values in your input field will be transformed. For example:

<pre><code><strong>2006-01-02 15:04:05 -> 1136214245
</strong></code></pre>

{% hint style="info" %}
You can try out operations with specific values using the **Input** field above the operation. You can enter the value in the example above and check the result in the **Output** field.
{% endhint %}
