Datetime.now () abnormality - Python

Question

I am serving a Python application through Django . In the application, I store the classic created field in several tables.

Here's what a field looks like in a Django form:

created = models.DateTimeField(blank=True, default=datetime.now())

---

Unfortunately, datetime.now () is not accurate. In fact, in the database, I have rowsets with the same timestamp.

The datetime.now () value changes every 30-45 minutes.

---

My Django is available on Windows Server 2005 for IIS6.

Help will be awesome!
