The `test_update_workcenter_adapt_finish_date` test was not consistent when the db was installed without demo data. The test was failing because the working hours were not the same and so the duration was different. To fix this we adjust the starting time of the work order so that it last exactly 30 minutes, and is not impacted by the working hours. runbot error : https://runbot.odoo.com/web#id=61595&cids=1&menu_id=405&action=573&model=runbot.build.error&view_type=form closes odoo/odoo#163238 X-original-commit: 5c49fc02f3fae0594b68d94bd8e9308bdbd21363 Signed-off-by: William Henrotin (whe) <whe@odoo.com> Signed-off-by: Robin Engels (roen) <roen@odoo.com>
