DateTimeOffset.FromUnixTimeSeconds() Method in C#

Last Updated : 27 Feb, 2019

DateTimeOffset.FromUnixTimeSeconds(Int64) Method is used to convert a Unix time expressed as the number of seconds that have elapsed since 1970-01-01T00:00:00Z to a DateTimeOffset value.

Syntax: public static DateTimeOffset FromUnixTimeSeconds (long seconds); Here, it takes a Unix time, expressed as the number of seconds that have elapsed since 1970-01-01T00:00:00Z (January 1, 1970, at 12:00 AM UTC). For Unix times before this date, its value is negative. Return Value: This method returns s date and time value that represents the same moment in time as the Unix time. Exception: This method will give ArgumentOutOfRangeException if seconds is less than -62,135,596,800 or seconds is greater than 253,402,300,799.

Below programs illustrate the use of DateTimeOffset.FromUnixTimeSeconds(Int64) Method: Example 1:

csharp

// C# program to demonstrate the
// DateTimeOffset.FromUnixTimeSeconds(Int64)
// Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        try {

            // Converts a Unix time expressed
            // as the number of seconds
            // that have elapsed since 
            // 1970-01-01T00:00:00Z to a 
            // DateTimeOffset value instance 
            // using FromUnixTimeSeconds() method
            DateTimeOffset value = 
               DateTimeOffset.FromUnixTimeSeconds(10000);

            // Display the time
            Console.WriteLine("DateTimeOffset is {0}", value);
        }

        catch (ArgumentOutOfRangeException e)
        {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}

Output:

DateTimeOffset is 01/01/1970 02:46:40 +00:00

Example 2: For ArgumentOutOfRangeException

csharp

// C# program to demonstrate the
// DateTimeOffset.FromUnixTimeSeconds(Int64)
// Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        try {

            // Converts a Unix time expressed
            // as the number of seconds
            // that have elapsed since 
            // 1970-01-01T00:00:00Z to a 
            // DateTimeOffset value instance 
            // using FromUnixTimeSeconds() method
            DateTimeOffset value = 
              DateTimeOffset.FromUnixTimeSeconds(254402300799);

            // Display the time
            Console.WriteLine("DateTimeOffset is {0}", value);
        }

        catch (ArgumentOutOfRangeException e) 
        {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}

Output:

Exception Thrown: System.ArgumentOutOfRangeException
