Timeline - addMarkedTimespan

When adding marked timespan, the last day in the view isn’t marked…

scheduler.addMarkedTimespan({
    start_date:  new Date(1401919200000),
    end_date:  new Date(2090,11,31),
    zones: "fullday",
    type: "dhx_time_block"
});


Hi,
try with the updated component from this post, viewtopic.php?f=6&t=36784#p113834
