# Changing Device date/time

## Introduction

The connector can only work when the device date/time is correctly set. This is due to the security applied on exchanged tokens and keys. 

When a connector has been installed on a device, at a moment which is in the past (other day/time), this results in the connector not working, even though the date/time has been set correctly on the system (post-installation). 

### Solution

To solve this problem the followin steps need to be executed:

* remove all device related keys
* restart the connector

#### Windows

Go to the installation folder of the connector:

`%localappdata%/Trust1Connector`

Delete all security relate files (selected below):

Those files are:

* device.priv
* device.pub
* device\_der.priv
* device\_der.pub
* device\_x509\_der.pub
* ds-ssl.json
* ds-txs.bck

{% hint style="info" %}
Those files will be automatically generated by the connector after the next step
{% endhint %}

Restart the connector by executing the **`'t1c-launch'`**

The process will be stopped, and restarted. The 't1c-launch' process must stop running, and the new processes will trigger the re-generation of the new keys.&#x20;

Due to this action, the device performs a new registration to the Distribution service, this can be verified in the **api.log** file (in the /Logs folder)

#### Mac OSX

Go to the installation folder of the connector:

`cd ~/Library/Application\ Support/Trust1Team/Trust1Connector/`

Open the folder in finder:

`open .`

Delete all security relate files (selected below):

Those files are:

* device.priv
* device.pub
* device\_der.priv
* device\_der.pub
* device\_x509\_der.pub
* ds-ssl.json
* ds-txs.bck

{% hint style="info" %}
Those files will be automatically generated by the connector after the next step
{% endhint %}

Use the terminal to open the connector installation folder:

`cd ~/Library/Application\ Support/Trust1Team/Trust1Connector`

Execute the t1c-launch to restart

`./t1c-launch --restart`

The process will be stopped, and restarted. The 't1c-launch' process must stop running, and the new processes will trigger the re-generation of the new keys.&#x20;

Due to this action, the device performs a new registration to the Distribution service, this can be verified in the **api.log** file (in the /Logs folder)
