The last marked element has a width of 1px, resulting in no marking of the last element… Any ideas to what might cause this?

How do you create timespan? please provide some code

start_date: new Date(2013,2,22),
end_date: new Date(2090,11,31),
zones: “fullday”,
type: “dhx_time_block”


Attached code works correctly in our samples. I can’t tell what the issue is without a complete demo
