Графические часы


Первый пример - это часы, отображающие время загрузки страницы (т.е. момент вызова скрипта). Используются методы объекта Date (getHours, getMinutes) и графические файлы, отображающие полученное время (имена этих файлов соответствуют цифрам - 0-9).

Во втором примере, отображающем текущую дату, также используются методы объекта Date (getDate, getMnth, getYear) и графические файлы, отображающие полученную дату (имена этих файлов соответствуют цифрам - 0-9).
