We are receiving nothing while working on REST API v2 version of WooCommerce. It was working fine when we are retrieving data from localhost which is http but now we have uploaded it to the server which is https. we have also clear the cache of wordpress. Still getting

stdClass Object ( [errors] => Array ( [0] => stdClass Object ( [code] => woocommerce_api_authentication_error [message] => Invalid Timesatmp )

)

) How can we covert the timestamp to server timestamp in the code Here is the function from where the timesatmp is generating public function get_oauth_params( $params, $method ) {

$params = array_merge( $params, array(
	'oauth_consumer_key'     => $this->consumer_key,
	'oauth_timestamp'        => time(),
	'oauth_nonce'            => sha1( microtime() ),
	'oauth_signature_method' => 'HMAC-' . self::HASH_ALGORITHM,
) );

// the params above must be included in the signature generation
$params['oauth_signature'] = $this->generate_oauth_signature( $params, $method );

return $params;

}
