Possible temp workaround for an issue where week view 'jumps' to the next upcoming week in conditions where it still ought to show the current week (due to timezone issues)

temp-fix-week-view-init-date.php

<?php
function temp_fix_42765( $date ) {
	global $wp_query;

	if ( ! empty( $wp_query->get( 'eventDate' ) ) )
		return $date;

	if ( defined( 'DOING_AJAX' ) && DOING_AJAX )
		return $date;

	try {
		$week_start = new DateTime( current_time( 'Y-m-d' ) );
		$offset = 7 - get_option( 'start_of_week', 0 );
		$week_start->modify( - ( ( $week_start->format( 'w' ) + $offset ) % 7 ) . 'days' );
	}
	catch ( Exception $e ) {
		return $date;
	}

	return $week_start->format( 'Y-m-d' );
}
