Is it possible to save datetime to DynamoDB?

I have the next code:

users_table = Table(users_table_name, connection=Core.aws_dynamodb_connection)
users_table.put_item(data={
  "login": login,
  "password": hashlib.sha256(password.encode("utf-8")).hexdigest(),
  "profile": profile,
  "registration_date": datetime.now() # PROBLEM IS HERE
})

But when I run it, it fails with error:

TypeError: Unsupported type "< type 'datetime.datetime' >" for value "2015-01-12 05:02:57.053131"

I've tried a lot of ways, but it seems that it isn't possible to save datetime to DynamoDB. Btw it works fine in MongoDB.

Is there any solution?

Okay, I see that DynamoDB does not support any date types. So the only solution is to use unix-like time as integer, or save date as string.

According to alejandro-franco response .isoformat() make the trick.

Just tested and this a working example:

CustomerPreferenceTable.put_item(
    Item={
        "id": str(uuid4()),
        "validAfter": datetime.utcnow().isoformat(),
        "validBefore": (datetime.utcnow() + timedelta(days=365)).isoformat(),
        "tags": ["potato", "eggplant"]
    }
)

According to the documentation: http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/JavaSDKHighLevel.html
