Description

Describes a time interval.

TTimeSpan is a data structure used for holding information about a period of time. A TTimeSpan object can be a positive or a negative time interval measured in days, hours, minutes, seconds, milliseconds, and ticks. The time period represented can be positive or negative and can range from the values stored in the read only properties MinValue to MaxValue. The smallest unit of time is a tick which is 100 nanoseconds. The largest unit of time is a day.
