Time clocks/Bundy clocks and Daylight Savings Time

Posted 22 March 2016 - 06:03 AM

After seeing a question in the C# forum where it looks like they are planning on building a simple time clock/Bundy clock and the recent Daylight Savings Time change, it got me to thinking, how does the time get recorded if you check into your shift at 10PM before the time change and check out at 6AM after the time change. Do you still get paid for 8 hours of work?

I'm sorry if the question is naive. I've never had to work shift work.

Is This A Good Question/Topic? 0

it depends how the time is saved. if you keep the time zone (which holds the DST info) or save it in a neutral format (UNIX timestamp) then any date/time library can accurately determine your work time.

Good point. But what about the paper analog, I assume that the stamps imprinted on a physical time card would just say:

since I never worked shifts with analog registration I canít tell what thatíd look like.

Many analog time clocks still require someone to change the time. But if the clock is smart enough to automatically change the time it should should smart enough to take the time change into consideration. Otherwise there is the possibility of manual intervention by management. This problem is also why the time change usually happens on the weekend in the wee hours of the day so as to minimize the disruption.

Edit: Also most time clocks also print the number of hours worked along with the times.

And I found my answer, as least with regards to US labor laws: Daylight Savings Time. Short answer is that the recorded time in and time out should match what the standard clock says, but the amount of time worked is the "real" amount of time: either 7 hours or 9 hours depending on whether DST is starting or ending.

I have worked hourly. They added a "bonus" hour during fall and you got screwed an hour during spring. I worked 3rd shift during those periods, too. But, you did get to leave the hour earlier, just not get the pay, which was understandable. The only ones that have to worry about it anyway are ones that are working during that 1-2 am period.
