Date error / too few arguments

On my posts page in each post is coming suddenly the following error message on the place of the date (I guess the problem is with date code):

on line 218 Warning: sprintf(): Too few arguments in /public_html/wp-content/themes/oxygen/library/functions/shortcodes.php

and in line 218 is:
$published = '<abbr class="published" title="' . sprintf( get_the_time( esc_attr__( 'l, F jS, Y, g:i a', 'hybrid-core' ) ) ) . '">' . sprintf( get_the_time( $attr['format'] ) ) . '</abbr>';

The whole part of that code there is:

function hybrid_entry_published_shortcode( $attr ) {
	$attr = shortcode_atts( array( 'before' => '', 'after' => '', 'format' => get_option( 'date_format' ) ), $attr );

	$published = '<abbr class="published" title="' . sprintf( get_the_time( esc_attr__( 'l, F jS, Y, g:i a', 'hybrid-core' ) ) ) . '">' . sprintf( get_the_time( $attr['format'] ) ) . '</abbr>';
	return $attr['before'] . $published . $attr['after'];
}

What I should change there? Thank you for all advices!
