Need information about the RTC user's profile User's "Work Environment" / "Work Location"

Hello,
We are  working with RTC 6.0.1.
I have a question about the the User's "Work Environment" / "Work Location".
I understand that the "Work Location" defined in the user profile are used to schedule work in the planning editors and views.
The work location doesn't affect the data / time displayed on the Work Items dates and Time.
I would like to see an explanation in the on-line help (or in another place) but I can't find this.
Have you a link to this information?

Thank You in advance
Pascal Jean
