Sparky..... Starting time is 8:00 am. Then you clock in at 8:01 am and work until 10:00 pm. Where I used to work, that would have been a mark (occurance) against me.

The only good purpose of a time clock is that employees get paid for the actual time on the job. Like if you work a few hours overtime and you are hourly or salary non-exempt, you get paid for those few hours. If you are on straight salary, you do not get paid for overtime.
Both scenarios can be accomplished by the employee filling in his or her own time sheet.

Punch clocks and whistles are for apes. Could you imagine having to drop what you are doing, when some stupid whistle goes off. Not me.
