I am trying to save multiple records in DB and have an array which looks like:-

```
$insert_data = array(
array(record 1),
array(record 2),
array(record 3)
)

```

Now, I tried two options:-

1. `Model::create($insert_data)` But it doesn't create any entry in DB.
2. `Model::insert($insert_data)` It's creating entry in DB with null datestamps.

I wanna insert multiple records with valid timestamps.

TIA
