Simple Alarm Clock wakes a computer from standby/hibernation to play an alarm
Purpose
The Simple Alarm Clock wakes a computer from standby/hibernation to play an alarm consisting of a file or website. It was meant to be very simple and backwards compatible all the way to Windows 98/NT 4.0
Requirements
* Windows 98,ME,NT (4.0),2000,XP, or Vista
* Internet Explorer 4.0 or greater (used for date control)
Notes
* You should set the alarm about two minutes earlier than you would like to wake, as your computer has to take time to wake up.
* Adjusts for Daylight savings time (So if you set it for 9:00 AM daylight savings time you will wake up at 9:00AM adjusted for daylight savings time)
