Text Labels for Animated Countdown

Is there a way to change the text labels for the animated countdown timer? For example could I have it say MIN instead of MINUTES, or SEC instead SECONDS? I found the following code in config-templatebuilder\avia-shortcodes\countdown.php. If this is the right place, then the question becomes: Can this be done in the child theme’s functions.php file so changes don’t get wiped out with theme updates?

Thanks guys!

$this->full_time_array = array(

	1 => array("interval" => 1000		, 'class'=>'seconds', 	'label' => __('Second', 'avia_framework' ),	'label_multi' => __('Seconds',  'avia_framework')),
	2 => array("interval" => 60000		, 'class'=>'minutes', 	'label' => __('Minute', 'avia_framework' ),	'label_multi' => __('Minutes',  'avia_framework')),
	3 => array("interval" => 3600000	, 'class'=>'hours', 	'label' => __('Hour',  	'avia_framework'),	'label_multi' => __('Hours',  	'avia_framework')),
	4 => array("interval" => 86400000	, 'class'=>'days', 		'label' => __('Day',  	'avia_framework' ), 'label_multi' => __('Days',  	'avia_framework')),
	5 => array("interval" => 604800000	, 'class'=>'weeks', 	'label' => __('Week',  	'avia_framework' ),	'label_multi' => __('Weeks',  	'avia_framework')),
	6 => array("interval" => 2678400000	, 'class'=>'months', 	'label' => __('Month',  'avia_framework' ),	'label_multi' => __('Months',  	'avia_framework')),
	7 => array("interval" => 31536000000, 'class'=>'years', 	'label' => __('Year',  	'avia_framework' ),	'label_multi' => __('Years',  	'avia_framework'))
