I am also getting same error, did you find solution .. Please share

Sorry, I’m still looking how to solve it.

Update...

I found out something today debuging this problem... Actually, two issues:

First: The problem is generated because there is a table where leaves are duplicated from hr_holiday, it's called resource_calendar_leaves, but it has a tz column that is not being filled when copying the value, as hr_holiday uses UTC and does not fill a tz, it leave it null. I set it Default as 'Utc'.

After fixing that, I updated all rows with that value and another problem p\showed up, "zero division". This was the second issue.

Second Issue: The work schedule cannot be split, it generates a zero division. We have a working schedule from 8am to 12pm and from 1pm to 5pm (8 hours total). So I created a schedule with 2 entries for each day, morning and afternoon. I changed it to one da from 8 to 5 and the problem disappear. But working days are not being calculated right. Still checking the last issue.

Hope this help somebody else and maybe somebody can help me with the last issue.

My issue got fixed . As you say holiday module stores in UTC format. When I changed date_from and date_to to Date instead of DateTime field, my error stopped appearing but leave hours comes up wrong.

Later I found that, If odoo doesn't find timezone set for user. It assigns UTC time to leave. So I changed all user timezone in user-> preference. Now everything works fine.

Remove all leaves,set timezone for user from preference. Now apply again.

Nice catch!

I'll try that.

Please how to set default time zone to all employees ?? or give other solution !!

Hi, i found the solution, you have just to give timezone to the user that is managing payroll, if it is undefined in preferences, that's my case
