Time difference : Hosting Server and client

hi All,I have asp.net/c# web project. How to manage the time difference between the server and clientFor instance, I am at India, and Server is located at UK. So if do any activity, like "comment on friend's photo" etc. the time stamps is UK's time. So if do some activity from India at 10.00 AM, the time stamp would be 5.00 AM. So if the user who sees his activity at 10.00 AM sees it as if it was done at 5.00 AM.If user whom he acted upon (like friend whose photo got the comment) too see 5.00 AM. this is ok if the friend is at UK, but causes confusion if he was at other time location like Australiahow to handle this

Round off time to the nearest minute

How would you round this up to the nearest minute? There isn't a built in function to do this so you have to use a little bit of maths to get there. There are 60 seconds in a minute. We already have 38 seconds on the clock. So we need to add on 60 - 38 = 22 more seconds.

What is the difference between "dynamic" and "object" keywords?

Let's take a quick look at the object keyword first. I'm not going to talk a lot about it because it's been around since C# 1.0. This keyword is nothing more than a shortcut for System.Object, which is the root type in the C# class hierarchy. (However, as Eric Lippert pointed out in his blog post, not everything in C# derives from object.) This is a powerful mechanism, since you can assign almost any value to instances of this type.

Performance Tests: Precise Run Time Measurements with System.Diagnostics.Stopwatch

Everybody who does performance optimization stumbles sooner or later over the Stopwatch class in the System.Diagnostics namespace. And everybody has noticed that the measurements of the same function on the same computer can differ 25% -30% in run time. This article shows how single threaded test programs must be designed to get an accuracy of 0.1% - 0.2% out of the Stopwatch class. With this accuracy, algorithms can be tested and compared.

Date and Time Functions in SQLSERVER

Date and time functions allow you to manipulate columns and variables with DATETIME and SMALLDATETIME data types.

1 DATEPART Function
2 DATENAME Function
3 DAY, MONTH, and YEAR Functions
5 DATEADD Functions
6 DATEDIFF Function
7 More SQL Server Functions

Data Types - Date and Time in SqlServer

Date and time values can be stored with either the DATETIME or SMALLDATETIME data type. The difference between the two is that SMALLDATETIME supports a smaller range of dates and does not give the same level of precision when accounting for time. The DATETIME data type can hold values from January 1st of 1753 to December 31st of 9999. The time is stored to the 1 three hundredths of a second and each value takes up 8 bytes of storage. The SMALLDATETIME data type can hold values between January 1st 1900 and June 6th of 2079. The time is tracked to the minute and each value takes up 4 bytes of storage. The majority of business applications can live happily with SMALLDATETIME, however, if you are in an environment where each second matters or you need to make estimates to the distant future (or past) then you have to resort to DATETIME. If you fail to specify the time when inserting a value into a DATETIME or SMALLDATETIME column, a default of midnight is used. If you fail to specify the date portion the default of January 1, 1900 is used.

How to programmatically add controls to Windows forms at run time by using Visual C#

.NET 4 Web Application Startup Time

I was chatting with Jonathan Hawkins and some of the folks on the ASP.NET team about performance and Jonathan mentioned the startup time for large ASP.NET applications is improved on .NET 4. There are some improvements in the CLR and in ASP.NET itself that helped. If you have a giant app, you should do some tests.
