Windows Registry Patch for Egypt 2016 Cancellation of DST

As you may know if you follow my blog, I previously wrote about the recent time zone chaos in Egypt [https://codeofmatt.com/2016/07/01/time-zone-chaos-inevitable-in-egypt/]. In this post I'd like to offer some guidance on what to do about it. On Microsoft Windows desktop or server

Time Zone Chaos Inevitable in Egypt

I would like to give everyone a heads up about the situation in Egypt. There is likely to be some confusion over the next week or so about what the local time is in Egypt, and it's entirely possible that the computers of the world may be erroneously

On the Timing of Time Zone Changes

What do Turkey, Chile, Russia, Venezuela, Azerbaijan, North Korea and Haiti all have in common? Time Zone Chaos! No, that's not the punchline to a joke. It's actually quite a serious problem. The biggest issue with time zones is not that they exist, nor that they

.NET

Beware the Edge (cases) of Time!

Ahh, time zones. There are so many wonderful traps to fall into. Consider this bit of code, from a recent blog post by Rick Strahl [http://weblog.west-wind.com/posts/2015/Feb/10/Back-to-Basics-UTC-and-TimeZones-in-NET-Web-Apps] : /// <summary> /// Converts a local machine time to the user's timezone time /// by

Five Common Daylight Saving Time Antipatterns of .NET Developers

It's 2015, and Daylight Saving Time is just around the corner. For most of North America, the clocks will "spring-forward" on Sunday, March 8th, stealing an hour of precious time from our daily routine. A few weeks later, the same thing will occur in much of

What is a Time Zone?

Almost any time you call up a friend, relative, or business associate in another part of the world, you'll realize that your time isn't always the same as their time, and the reason is "time zones". You probably know a little about time zones

Localized time zone names in .NET

If you've ever used the TimeZoneInfo class in the .NET framework, you probably know that it has properties intended for display of a time zone to the end user. Specifically, these are the DisplayName, StandardName, and DaylightName properties. However, there are a few problems with these. * Unlike many

Russia 2014 Time Zone Changes

Are you prepared for Russia's major time zone changes [http://www.timeanddate.com/news/time/russia-abandons-permanent-summer-time.html] ? If you are either in Russia yourself, or interact with Russian customers or users, you will need to ensure your time zone data has been updated before the changes go into

Pluralsight - Date and Time Fundamentals

I'm happy to announce that the video course I've been working on for Pluralsight, "Date and Time Fundamentals" [http://pluralsight.com/training/Courses/TableOfContents/date-time-fundamentals] has finally been released! Here's one of my favorite slides: But seriously - There's a

UTC vs GMT

I'm not going to dive into a history lesson here. This is about practical, usable information in today's modern world. You can always go read more about GMT [http://en.wikipedia.org/wiki/Greenwich_Mean_Time] and UTC [http://en.wikipedia.org/wiki/Coordinated_Universal_Time]

Egypt goes back to Daylight Saving Time

With only a week's notice, the government of Egypt has decided to go back to daylight saving time - effective today. That's right, it was casually announced [http://english.ahram.org.eg/NewsContent/1/64/100735/Egypt/Politics-/Egypts-government-to-reapply-daylight-saving-time-.aspx] on May 7th, and went into

Time Zone Abbreviations

What does the abbreviation EST mean? I'm sure you've seen that before. If you live in the United States, you might recognize it as "Eastern Standard Time", which is a time zone used in places like New York City, Washington D.C., and Miami.

Handling Birthdays, and Other Anniversaries

How old are you? Simple question, yes? Perhaps. But the answer could change depending on the granularity of the question, and on your perspective. To answer "how many minutes old are you?", we need a lot more information than might be readily available: * Your date and exact time

Working with Time Zone Names in .Net

UPDATE: I've made a library to do this work for you.

Windows Azure Scheduler

Microsoft announced today a new managed service for Windows Azure: The Windows Azure Scheduler [http://www.windowsazure.com/en-us/services/scheduler/]. This is basically an enterprise job scheduler, such as Quartz.net [http://quartznet.sourceforge.net/], but operated as a simple managed web service. Basically, you can set up a

JavaScript Date type is horribly broken

JavaScript dates have always been a bit funny. As a .Net developer, there was a bit of a mind-shift for me, because they are inherently different than types like DateTime or DateTimeOffset. But I won't spend too much time on what they are not, lets just talk about
