Timezone issues with schedule/calendar list

I have been using sportspress for over a year, but have always had issues with the timezone when a calendar is displayed. It always seemed to ignore timezones (so it would should tomorrow even though it was still today, because my timezone was -6 from gmt).
I submitted a request to the Pro support (i’m a registered/paying user) but did not get a satisfactory response. (basically didn’t think it was an issue).

Context:
I have timezone set correctly in WordPress (and Sportspress, since it uses the same value). However:
– mysql has a different timezone (off by 1 hour), and I can’t change it because it’s on a shared hosting account.
– php has a different timezone (UTC), and I can’t change that because it’s a shared hosting account.

What I found that makes it work correctly is by changing class-sp-schedule.php to call date_i18n() instead of date() when getting the date values for the schedule list:

		if ( $this->date !== 0 ):
			if ( $this->date == 'w' ):
				$args['year'] = date_i18n('Y');
				$args['w'] = date_i18n('W');
			elseif ( $this->date == 'day' ):
				$args['year'] = date_i18n('Y');
				$args['day'] = date_i18n('j');
				$args['monthnum'] = date_i18n('n');
			elseif ( $this->date == 'range' ):
				add_filter( 'posts_where', array( $this, 'range' ) );
			endif;
		endif;

Not sure if I know the overall ramifications of this, but it makes the list of events work correctly. If there is some other setting or fix that I am missing, please let me know.

Thanks!
