# Setting the TD Import Time Format for a Windows Batch File

If you need your date data formatted a certain way so that it works well with Treasure Data there are ways that you can do so. Particularly, if you are importing CSV formatted data on Windows and doing a batch import, you can add the `--time-format` parameter to your import statement. For Example:


```bat
td import:prepare --format csv --column-header --time-column 'date' \
--time-format '%%Y-%%m-%%d' t
```

`%` is a recognized environment variable, so you must use `%%` to set it.
