Build a solid foundation of working with Date and Time with this course Almost all the software works with date and time in one form or another. Some programs of course need to work with date and time more than other. However date and time hide many pitfalls even in very simple scenarios. We all know that security and logging are regular aspects of almost any program. There is a wise phrase that sounds like: Developers recall about security when it is too late. The same can be said about date and time. Most developers don't even imagine how many bugs are hiding behind the simple face of date and time. Those bugs are sitting in programs and waiting for their moment to blow up your production code causing very unfortunate repercussions. That's why working with date and time is the full-fledged and very important aspect of software development. Have you watched magnificent enlightening TV Shows by BBC? This course in some parts is like those BBC shows because you'll learn many interesting surprising facts. Besides being familiar with peculiarities of working with date and time you can write much more reliable and maintainable applications. Content and Overview

This course is aimed at all kind of developers. It provides solid theoretical base reinforced by practical material.

We start with basics of date and time. I'll show you some real cases when bugs related to date and time caused unpleasant consequences event deaths of people. You'll learn why the hell Gregorian calendar was introduced why the 5th of October 1582 doesn't exist at all. And did you know that actually a minute can last more than 60 seconds? Yes you heard that a minute can last more than 60 seconds. You'll learn what is UTC GMT what is the difference between them and how time gets synchronized between computers all over the world. And by the way what is time at all how humanity measures it? After that you'll be introduced to the concept of time zones you'll learn about different standards that regulate date and time formatting. You'll learn what is Epoch Time and Unix Time. Finally you'll understand the difference between different date-time scopes and perspectives.

The next section is dedicated to Time Zones where you'll learn about daylight saving time and different very odd case with time transitions back and forth. I'll give you a full definition of a time zone. You'll learn more about providers of time zone information: IANA and Microsoft. You'll learn many interesting facts and what fallacies exist about time zones.

The third section is all about date and time related types from BCL in .NET. You'll learn about DateTime DateTimeOffset TimeZoneInfo TimeSpan Calendars and Stopwatch. I'll show you that DateTime hides many pitfalls. You'll learn that actual precision of BCL types is not equal to 100 nanoseconds as declared in the documentation. You'll see how many calendars exist and what we can do with them. The third section reveals all the problems with the types built-in to BCL so in the next section you'll learn about a third-party library called Noda Time.

Yes a whole section is dedicated to the Noda Time library. You'll learn about features provided by this library. You'll get an overview of all the core types such as: LocalTime LocalDate LocalDateTime Instant Interval Duration ZonedDateTime and others. You'll also learn how to write unit tests on code which uses date and time values with the help of Noda Time.

The whole section is dedicated to best practices of working with date and time. You'll see some astonishing things like arithmetic on dates and problems of birthday calculation. You'll learn the problems related to parsing and how to overcome them. I'll show you the problems of events schedulingand what to do to avoid common mistakes. You'll learn about date and time ranges intervals is a separate peculiar topic. I'll also show some additional best practices.

In other words an exciting journey is waiting for you just take it relax and enjoy.

So in short the course covers the following topics:

• Date and Time Fundamentals: Gregorian calendar UTC GMT Atomic Time How Computers Store Time NTP Date and Time Formats based on Standards and Specifications Epoch Time and Unit Time Date and Time Scope and Perspective
• Time Zones: Definition (complex one) Daylight-Saving Time (DST) Providers such as IANA or TZDB and Microsoft
• Date and Time in .NET: DateTime DateTimeOffset TimeZoneInfo TimeSpan Calendars Stopwatch and many intrinsic details.
• Noda Time: overview core types unit testing
• A great number of best practices of working with Date and Time: arithmetic on dates parsing calculating of birthdays scheduling events date formats ranges and other.

In the end we will recap what you have learned.

How long is this course: The course is around 3 hours. All are video lectures. You will be able to download all the slides and code samples used in the course.
