# Time entries

Time entries are a collection of hours tracked per project and user. There are two types of time entries: **suggested** and **confirmed**.

**Suggested (unconfirmed) time entries**

Suggested time entries (also known as unconfirmed time entries) are created by Resource Management by Smartsheet as a result of resources being assigned to a project. These are identifiable by the `is_suggestion: true` attribute on the time entry objects. Suggested time entries are read-only and are kept up to date by Resource Management by Smartsheet as the corresponding assignments are updated. They are not returned by the API by default and must be requested using the `with_suggestions=true` parameter on the GET API call to fetch time entries.

**Confirmed time entries**

Confirmed time entries are what a user (or the API) has explicitly created to indicate that they have spent some time working on a project. Note that just like in the application UI, you cannot create new confirmed time entries for managed resources via the API. You can read suggested time entries for all users via the API.

**Bill rates**

Time entries have an associated bill rate attached to them. When a new time entry is created, Resource Management by Smartsheet will determine the appropriate bill rate for it (based on your account and project settings) and assign a values. When reading time entries, you can see this assigned bill rate.
