You can solve this issue in 2 simple steps. 1) go to user profile -> My Profile -> Preferences -> Timezone (select your Timezone).  2) go to Settings -> Technical -> Working Times -> select the right working Times -> Timezone (select your Timezone).  This will solve this issue.

Hi

First make sure that you set time zone correctly. Then go to employee module and select the employee who has the problem with time off. In work information tab set the working time of company for employee. 

Any update on this? i have the same problem.

UPDATE:

I selected only days on calendar, but time was added to the record. You can see it down in scheduled activity.

we have the same behaviour (running on latest odoo v13). nobody got a solution for this?

Check timezone of your user in preference and timezone of the employee attached to it. Every timezone should match for correct calculation if its same you will not get such bug

Hi,

I think such an error was there has got fixed already. Can you try to reproduce the issue in the odoo runbot and see, whether you are able to get the same in runbot. If you are not getting this in runbot , pull the latest odoo v13 code and try.

Thanks
