### Baseline Start / End date field

This field determines the start/end position of the task's baseline on the timeline. The following [field types](https://confluence.atlassian.com/adminjiraserver/configuring-a-custom-field-938847235.html) can be synchronized:

- "Date Picker"
- "Date Time Picker"

> ℹ️ <span style="color: #003366">"Date Time Picker" fields are only available on Jira server versions.</span>

Disabling synchronization with Jira is possible by selecting the '--Not Synchronized--' option.
