Vaadin 14 chart timezone offset

Good afternoon!
I read data from database and send them to chart and grid.
Data has 4 fields, their type: LocalDateTime, int, int, int.
In grid the column datatime is displayed correctly according to the timezone, but in chart timezone is not counted and is displayed three hours earlier.
How to solve this problem?
Probably I should set for the chart the timezone offset.
Thank you!
