One of the best engineers I've ever worked with was constantly late, but she was so good at the rest of her job that the bosses always covered from her and it became more of a running gag.
I'm so glad I don't have to worry about what time I show up for work. When I get there my day starts and when I leave it's over. My start time is between 6:00AM and 9:00AM and I'll leave anywhere from 3:30 to 7:00. Can't imagine being concerned about 15 minutes making a difference.
^^Me too. I start when I get there. And quit when I feel like going home. That said, I'm nearly always in before 8:00am and seldom leave till after 6:00pm. Was in before 7:00am this morning.
