TimeSpan Structure
.NET Framework Class Library
TimeSpan Structure

Represents a time interval.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)
 Syntax
Visual Basic (Declaration) 
<SerializableAttribute> _
<ComVisibleAttribute(True)> _
Public Structure TimeSpan _
    Implements IComparable, IComparable(Of TimeSpan),  _
    IEquatable(Of TimeSpan)
Visual Basic (Usage) 
Dim instance As TimeSpan
C# 
[SerializableAttribute]
[ComVisibleAttribute(true)]
public struct TimeSpan : IComparable, IComparable<TimeSpan>, 
    IEquatable<TimeSpan>
Visual C++ 
[SerializableAttribute]
[ComVisibleAttribute(true)]
public value class TimeSpan : IComparable, 
    IComparable<TimeSpan>, IEquatable<TimeSpan>
JScript 
JScript supports the use of structures, but not the declaration of new ones.
 Remarks

A TimeSpan object represents a time interval, or duration of time, measured as a positive or negative number of days, hours, minutes, seconds, and fractions of a second. The largest unit of time used to measure duration is a day. Time intervals are measured in days for consistency because the number of days in larger units of time, such as months and years, varies.

The value of a TimeSpan object is the number of ticks that equal the represented time interval. A tick is equal to 100 nanoseconds, and the value of a TimeSpan object can range from MinValue to MaxValue.

A TimeSpan value can be represented as [-]d.hh:mm:ss.ff, where the optional minus sign indicates a negative time interval, the d component is days, hh is hours as measured on a 24-hour clock, mm is minutes, ss is seconds, and ff is fractions of a second. That is, a time interval consists of a positive or negative number of days without a time of day, or a number of days with a time of day, or only a time of day. For example, the text representation of a TimeSpan object initialized to 1.0e+13 ticks is "11.13:46:40", which means 11 days, 13 hours, 46 minutes, and 40 seconds.

The TimeSpan type implements the System..::.IComparable and System..::.IComparable<(Of <(T>)>) interfaces.
 Examples

The following code example creates several TimeSpan objects and displays the properties of each.
