Sorry my mistake,
Here what you have to change:
Open /modules/extcal/daily_view.php
look for line 58:
$start_date = $start_day_name." ".$start_day." ".$start_month_name." ".$start_year." à ".$start_time;
Change to
$start_date = $start_day_name." ".$start_day." ".$start_month_name." ".$start_year." at ".$start_time;
Here the second one same file and look for line 68:
$end_date = $end_day_name." ".$end_day." ".$end_month_name." ".$end_year." à ".$end_time;
Change to:
$end_date = $end_day_name." ".$end_day." ".$end_month_name." ".$end_year." at ".$end_time;
Because this module was made by a french person. It's not a funny symbol, the french "à" mean "at" or "to".
