After you create a time period in Usage Analyst, it's easy to edit it. Time periods may not overlap. For example, if you have one time period running from 12:00 pm – 5:00 pm, the next time period must start at 5:01 pm.
To edit a time period:
Did you know? You can enter the start and end times in either the 24-hour clock or am/pm format. If you use the am/pm format, Usage Analyst changes it to the 24-hour clock.
If you no longer need a time period, you can delete it.
