Description

+

+ The operator record Duration is used for elapsed time. + This can be the time between given by DateTime records + (i.e. by subtracting them) or a manually specified duration. +

+

+ There are multiple constructors provided to create a Duration element. + See the examples below for details. +

+ +

Here is a brief summary, what the Duration operator record is capable of:

Example

+ +The examples below demonstrate the different methods to create a Duration record. + +
+
+import Modelica.Utilities.Time.Duration;
+
+// Create Duration records from direct input
+Duration();                                      // create Duration record using default constructor, which is fromInput
+Duration.'constructor'.fromInput(hours=10);      // explicit call of constructor
+Duration(days=1, seconds=100);                   // automatic selection of constructor fromInput
+
+// Create Duration records from two DateTimes
+import Modelica.Utilities.Time.DateTime;
+dt1 = DateTime.now();
+dt2 = DateTime.now();
+Duration.'constructor'.fromDateTimes(dt1, dt2);  // explicit call of constructor
+Duration(dt1, dt2);                              // automatic selection of constructor via data type
+Duration(dt1=dt1, dt2=dt2);                      // automatic selection of constructor via names
+
+// Create Duration records manually using the elapsed seconds since the given epoch year
+Duration.'constructor'.fromSeconds(1);           // explicit call of constructor
+Duration(totalSeconds=1.5);                      // automatic selection of constructor via name
