JScript suports the use of structures, but not the declaration of new ones.
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 interfaces.
The following code example creates several TimeSpan objects and displays the properties of each.
