You can choose to not round time at all, round time to the nearest five minutes, or round time to the nearest fifteen minutes.
There are a few things to note about how the feature works. The feature uses a concept called "nearest rounding". So it will round to the nearest fifteen minute increment (i.e. :00, :15, :30, :45). 50% and up rounds up and 49% and down rounds down.
We use a "zero rule" that says any rounding that will create a time segment equal to zero will not occur. For example, if any employee clocks in for only five minutes from :01 to :06, and you have the fifteen minute rounding rule turned on, then the time will NOT be rounded since both times would be rounded down to :00 resulting in a time segment equal to zero.
When an administrator makes an edit to a time, it will not be rounded. Also, any time added by an administrator using "Add Time" will not be rounded.
The feature is non-destructive to the original exact (to the minute) time data, and acts as a filter for display and reporting purposes. So you can turn it on or off at any time to restore the original non-rounded times.
Turning the feature on or off at any moment in time will cause all times both in the future and past to be displayed per the chosen setting.
