Trouble getting the date

Question

This sounds like a joke, but i can't get the date right.

**In my machine, shows the date correctly, but when running it on Railway, it just shows day before**
I guess i could add one but that just seems incorrect. I'm sorry if this is a newbie problem but i just can't solve it.

```python
madrid_tz = pytz.timezone('Europe/Madrid')
DATE = datetime.datetime.now(pytz.utc).astimezone(madrid_tz).strftime('%Y-%m-%d')
BACKUP_FILE = os.path.join(f"backup_{DATE}.sql")
```
