using System;

class FromSecondsDemo
{
    static void GenTimeSpanFromSeconds( double seconds )
    {
        // Create a TimeSpan object and TimeSpan string from 
        // a number of seconds.
        TimeSpan    interval = TimeSpan.FromSeconds( seconds );
        string      timeInterval = interval.ToString( );

        // Pad the end of the TimeSpan string with spaces if it 
        // does not contain milliseconds.

Remarks

The value parameter is converted to milliseconds, which is converted to ticks, and that number of ticks is used to initialize the new TimeSpan. Therefore, value will only be considered accurate to the nearest millisecond. Note that, because of the loss of precision of the Double data type, this can generate an OverflowException for values that are near but still in the range of either MinValue or MaxValue, This is the cause of an OverflowException, for example, in the following attempt to instantiate a TimeSpan object.

// The following throws an OverflowException at runtime
TimeSpan maxSpan = TimeSpan.FromSeconds(TimeSpan.MaxValue.TotalSeconds);

// The following throws an OverflowException at runtime
let maxSpan = TimeSpan.FromSeconds TimeSpan.MaxValue.TotalSeconds

' The following throws an OverflowException at runtime
Dim maxSpan As TimeSpan = TimeSpan.FromSeconds(TimeSpan.MaxValue.TotalSeconds)
