Then calls to the getHours, getMinutes, and getSeconds methods assign the value of the current hour, minute, and second to hour, minute, and second.\n\nThe following statements build a string value based on the time. The first statement creates a variable temp. Its value is hour % 12, which is hour in the 12-hour system. Then, if the hour is 0, it gets re-assigned to 12, so that midnights and noons are displayed as 12:00 instead of 0:00.\n\nThe next statement appends a minute value to temp. If the value of minute is less than 10, the conditional expression adds a string with a preceding zero; otherwise it adds a string with a demarcating colon. Then a statement appends a seconds value to temp in the same way.\n\nFinally, a conditional expression appends \"P.M.\" to temp if hour is 12 or greater; otherwise, it appends \"A.M.\" to temp.\n\n{{PreviousNext(\"Web/JavaScript/Guide/Numbers_and_strings\", \"Web/JavaScript/Guide/Regular_expressions\")}}\n\nAttribution: Adapted from MDN Web Docs under CC-BY-SA-2.5.
