DateTime

Dealing with Dates and Time is a complex issue in IT world. Correctly handling date and time information requires considering the nature of what we are storing as time information and how to apply it to a specific location. This includes calendars, time zone information, daylight-savings periods, and offsets for comparison of different values.

Below are some good references on this topic.
