DateTimeOffset.ToUnixTimeSeconds Method is used to return the number of seconds that have elapsed since 1970-01-01T00:00:00Z. Before returning the Unix time, this method will convert the current instance to the UTC. And also, it will return a negative value for the date and time values before 1970-01-01T00:00:00Z.
Syntax: public long ToUnixTimeSeconds ();
Return Value: This method return the number of seconds that have elapsed since 1970-01-01T00:00:00Z.
Below programs illustrate the use of DateTimeOffset.ToUnixTimeSeconds() Method:
Example 1:
// C# program to demonstrate the // DateTimeOffset.ToUnixTimeSeconds() // Method using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
// creating object of DateTimeOffset
DateTimeOffset offset = new DateTimeOffset(2017,
6, 1, 7, 55, 0, new TimeSpan(-5, 0, 0));
// Returns the number of seconds
// that have elapsed since 1970-01-01T00:00:00Z.
// instance using ToUnixTimeSeconds() method
long value = offset.ToUnixTimeSeconds();
// Display the time
Console.WriteLine("Returns the number of"+
" seconds : {0}", value);
}
} |
Returns the number of seconds : 1496321700
