Add a button to automatically timestamp EXIT TIME when a visitor leaves
Hi, I´m making an app to control how much time people who visit our company stay at our facility wheter waiting for someone or been helped with something.
As you may see from the picture (sorry is in spanish), I have already set various fields for who is the visitor coming from, which department is visiting, who helped him and some notes about the visit. The HORA ENTRADA field (TIME IN) is set with a timestamp when created, but I need that our recepcionist can be able to press a button, in this case it should be SALIDA (EXIT) to set the Hora Salida (TIME OUT) so she doesn´t has to type anything and it can be as automated as possible. Some extra help if you could tell me how to calculate the total time spent at our company with field Tiempo Visita (VISITING TIME)
Does anyone has any idea how to do this ? I bet it is something very easy for many, but my mind is blocked !!!
