Bear in mind that this is your employee's gross weekly pay, that is, before taxes and other deductions. So, although the actual hours worked are 8 hours and 10 minutes, the rounded work time of the employee from our example will be 8 hours and 15 minutes. On the other hand, you'll round up their clock-out time to will have to be rounded to 4. We use decimal hours for two reasons…. There are fond memories I have at the movies, so I am not judging anyone who still goes. Imagine how long it takes to do timesheet conversion for all your employees every week or month. Specifically, the Lancet study—which followed 130, 000 people in different countries over an average of seven years—found those who put in at least 2. They are more precise - decimal hours are almost 2 times more precise than minute hours. On the other hand, if your employees get less than they should, you risk litigation and being slapped with hefty fines. Let's say an employee's hourly rate is $15, and they worked a total of 24.

The early computer systems simply mimicked their predecessors. And that's the root of the problem. This is particularly important if you use paper timesheets and manually record employee hours. As you can see, when rounding time, you have to take both clock-in and clock-out time into account. Why use decimal hours? But I love movies, specifically in my own home. We'll start with our two-fifths. The next time clocks were the old school wall mounted punch clocks. A Bit Of Time Clock History. Therefore, you'll have to round down their time to 8. 5 hours) each week doing physical activity to become a far healthier human being. In short, the employee from this example worked 2.
