When reading a BLF file with python-can, the parsed timestamps are always 8 hours later than what is shown in Vector CANoe.

### Describe the bug

When reading a BLF file with python-can, the parsed timestamps are always 8 hours later than what is shown in Vector CANoe.

### To Reproduce

1.Create or record a BLF file with CANoe.
2.Open the BLF file in CANoe → check message timestamps (example: 13:00).
3.Open the same BLF file with python-can using the following script:
`import can
import datetime

blf_file = "test.blf"

with can.BLFReader(blf_file) as log:
for msg in log:
t_raw = datetime.datetime.fromtimestamp(msg.timestamp)
print(f"Time: {t_raw}, Relative seconds: {msg.timestamp}")`

4.Observe that the timestamps printed by python-can are +8 hours compared to CANoe (example: 21:00).

### Expected behavior

Timestamps should match those shown in CANoe (e.g., 13:00).

### Additional context

OS and version:Windows 11
Python version: Python 3.11.7 (tags/v3.11.7:fa7a6f2, Dec 4 2023, 19:24:49) [MSC v.1937 64 bit (AMD64)] on win32

Traceback and logs

```python
def func():
return "hello, world!"
```

Comece pelo ponto de entrada BLFReader e reproduza a conversão de timestamps usando o script da issue em um arquivo BLF criado pelo CANoe. Compare o resultado com o horário exibido pelo CANoe e determine o comportamento esperado do fuso horário ou do offset; considera-se concluído quando os timestamps analisados correspondem ao CANoe para o exemplo relatado.
