| Time Intervals |
The intervals that are used to set up peformance indicators are accessed from the Time Interval module. The default list of intervals (figure 1) can be deleted, edited or added to.

Figure 1: Default List of Time Intervals.
To delete a record, click the "delete" link next to the record. A popup message will appear asking you to confirm that you wish to delete it. Press "OK", and its status will change to "deleted".
Records are split up into pages. Click a page number link to view another page of records.
The number of your current page is highlighted in bold red text.
If there are a lot of pages, numbers will appear in a list that you can scroll along.
To change the number of records shown at a time, select a different number from the drop-down
list at the top of the page.
Checking the "Show Deleted, Suspended, Pending" checkbox will cause the list of records to include these records along with those currently open. Leaving the checkbox blank will cause the list only to show records currently open.
Click "Add" to add a new interval, or click an existing type to view/edit it. You can create your own intervals from multiples of days, weeks, months or years (figure 2).

Enter or update the interval's name, definition and status, then press the "Add" or "Update" button to save your data. Press the "Cancel" button to return to the list of records, losing any unsaved changes.
Only use whole numbers in the first "definition" field.
If you delete an in-use interval, you will be able to complete data entry for instances of measurements using that interval. However, the interval will not be available for use with new performance indicators. Pending and suspended intervals will also not be available for use with new performance indicators.
Note: editing intervals that are in use may affect your data.
