TimePicker is a custom server control tool for showing time in specific ways. It consists of three main DropDownList for showing hour, minute and second. As default it shows the current time. We have the choice of showing time with AM/PM mode or just show it by 24 hour mode. . For example, we could have, 10:20:34 PM or 22:20:34. In the AM/PM mode we also have a DropDownList for selecting AM or PM. It is also possible to hide the second part of the TimePicker. We could also define intervals for minutes and seconds of TimePicker. For example, if we decide that the minutes are shown with the interval of 15 minutes then the minute DropDownList will only contain 0, 15, 30 and 45 values.
