Why all the effort when you can just change the time manually?
Ever try to teach a computer illiterate (no disrespect intended) how to change anything?
From my experience as a technical instructor, a vast amount of folks that own a computer have no clue. I spend much of my time explaining why and how they should use firewalls, anti-virus and other general computer safety precaution software. And yet, many of my after job call outs are the result of these same people not heeding my warnings.
And you expect these folks to know how to reset their system clocks … give me a break.
Because people like me actually rely on my computer to tell me when to change all the clocks. Sometimes I just don't hear about it anywhere else. When I start my computer and it says "Windows has adjusted for daylight savings time" then that is my cue.
Because Bill Gates will attempt to change it on the old dates, anyway.
