Work Hours, Timecards & Shifts

A timecard turns raw clock-in and clock-out times into a number someone gets paid on, and that translation has several places where two reasonable-sounding methods produce different totals: whether an unpaid break gets subtracted before or after rounding, whether a shift that crosses midnight is one entry or two, and what rounding rule (to the nearest minute, to the nearest quarter hour, or something else) applies at each clock event. This category covers hours-worked totals, timecards across a pay period, break deductions, and shift-length questions, including the overnight and split-shift cases that break a naive subtraction.

Paid time and elapsed time are not the same number

The elapsed time between clocking in and clocking out is not automatically the paid total; unpaid breaks, rounding policy, and any overtime threshold all sit between the two. Results here separate the raw elapsed span from the paid figure explicitly, rather than collapsing them into one number and hiding which adjustments were applied.

Rounding has to be shown, not just applied

A rounding rule (up, down, or to nearest, at a stated interval) can shift a weekly total by a meaningful amount over many clock events. Where rounding applies, the result states the rule and, where useful, what the total would look like without it, so the effect of the rounding policy itself is visible rather than buried in the final number.
