I would like to understand what drives input for In & Out time on time card as shown below,

 My understanding is it takes data from Day type, we have 24 hour clocking so we’ ve below day type setup,

Also, when I create absence request, system considers 2 days even when I register for single day; could you please advise what should be the correct setup to avoid this ?(In out timings on time card and vacation for 1 day)
