We need to include header into our C++ program in order to manipulate date and time. For example, if the Kind property of the date and time value is DateTimeKind.Local, an exception is thrown if the TimeZoneInfo object passed as a parameter to the method is not equal to TimeZoneInfo.Local. An abstract base class for time zone information objects. Note The letters in the format string specify the output.

They provide support for time acquisition, conversion between date formats, and formatted output to strings. C++ inherits date & time functions and structures from C language. If the date and time value does not represent either the local time or UTC, the ToUniversalTime method will likely return an erroneous result. I am working on a C# project in which user can change datetime column time zone using its profile page. So, we summarise the above data as, All columns got assigned values per the data types, for example, for the first column – YEAR – though we inserted using ‘now()’ function which is the current timestamp, the value that got inserted is just the year part of the current date time – i.e. Example: DateTime dt = new DateTime (2014, 05, 01, 12, 05, 54); Console.WriteLine (dt.ToString ()); Output: 5/1/2014 12:05:54 PM.
