To edit or view a time period
Click the name of a time period (for example, “Working hours”).
You can assign the time zone for the period, which is typically the default for the policy or connection where the users are located (see Proxied connections).
The dark area defines the actual time period. Each division is a 15 minute period and can be set with either a single click or by clicking and dragging to produce a wider area. As you roll your mouse over the area, the absolute time is displayed below the time chart.
