Hi,

See the below parts form odoo qweb documentation: https://www.odoo.com/documentation/15.0/developer/reference/backend/reports.html

Reports are web pages
Reports are dynamically generated by the report module and can be accessed directly via URL:

For example, you can access a Sale Order report in html mode by going to http:///report/html/sale.report_saleorder/38

Or you can access the pdf version at http:///report/pdf/sale.report_saleorder/38

it does not matter what timezone the datetime object is actually in (including no timezone), its timezone will unconditionally be set to UTC before being adjusted to the user’s

Thanks
