class DateTime
 

Detailed Description

Represents a time interval.

Note that the TimeSpan class is meant to express a time interval independently of the concrete starting DateTime and end DateTime and hence can not be expressed in years and month. For that use case, use the Period class instead.

Remarks
Time values are measured in 100-nanosecond units called ticks.
Todo:
  • Add method for parsing custom string formats.
  • Add method for printing to custom string formats.
