Multi-Vendor different Time Zones for each storefront

Hello,

according to documentation and settings in admin panel, using 2 or more storefronts on multi vendor, we cannot set different time zones for each storefront.

What is the solution for it? does there exist any add on or system actualization, which allow managing different time zone separately for each storefront. e.g. Storefront (a) has time zone London and Storefront (c) has time zone of New York

Thank you very much in advance
