How is it different from punch in at 8pm and out at 4am?
>We use 00:00 vs 24:00 in our software, We receive 00:00 from the punch clock, but in the back to do time calculation we translate to 24:00, because for example punch in at 20:00 and out at 00:00 does not lend itself to an obvious calculation, so we translate to 24:00 temporarily to find out the time elapse.
