WinCalendarTime, customize your windows clock

Have you ever said to yourself, "If only I could display the date as well as time in the windows task bar without making it take up more than one row?" Well I used to, until I discovered WinCalendarTime a few months ago. Its a simple windows C program that allows you to format the time display your windows desktop. You can chose to hide either the date or the time and there are three date formats. You can also display seconds of the minute. Unfortunately, it does not allow me to display the date in ISO format (e.g. 2009-04-18 23:34) . One day I might write a patch for that.
