And it gets worse from there, not every country celebrates Daylight Savings
on the same day as the US.. PLUS - some don't participate at all. So keeping
a database of start and end times would be a mess.. because also consider
many countries have multiple time zones - so you'd almost need to know the
postal code of where you are, to geomap which zone you are in..

Depending on your app, it's best to store everything in UTC/GMT/Zulu 0:00
time.. for DISPLAY purposes, you could just have the user choose what thier
offset is? Or.. if it's on the local machines (which is ideal) - you can
just do .ToLocalTime() to the UTC and it handles it automatically..
