Hello everyone,

I hope you are having a good day. I have encountered an issue with the code bellow.

PROBLEM:

Despite the output being as expected, when I navigate to the Attendances module, I notice that the checkout times for the employees are not correct. The employee was checked out at 15:00 (instead of 14:00), and the admin was checked out at 19:00 (instead of 18:00). I believe two factors might be causing this issue, but I am uncertain how to resolve them:

1. The server's timezone and the current time appear to be incorrect. The TZ is set to None, and the current time is defaulting to GMT 0, as indicated in the output. This might be causing Odoo to adjust the checkout times by adding +01:00:00 to them.

2. We are currently observing daylight saving time in Lisbon/Europe, which could also be contributing to the discrepancy in checkout times.

I attempted to address this by forcing the functions to use the Administrator's timezone instead of the server's timezone, but it did not resolve the issue. I even tried to alter the hidden user OdooBot, and setting up a timezone, without results.

If anyone has insights on how to rectify this situation, I would greatly appreciate your assistance.

Thank you in advance, and have a nice day.

Best regards,
