Modelica print current time

How can I print the current date and/or time to a file (e.g. log file, or csv file) from Modelica? Do I need external code for this? I was not able to find any example code in the Modelica Standard Library.

  • https://build.openmodelica.org/Documentation/Modelica.Utilities.Streams.print.html

    You would need to add this to your equation or algorithm section:

    .Modelica.Utilities.Streams.print(String(time));

    For local system time use: https://build.openmodelica.org/Documentation/Modelica.Utilities.System.getTime.html

    model GetTime
  Integer ms;
  Integer sec;
  Integer min;
  Integer hour;
  Integer mday;
  Integer mon;
  Integer year;
algorithm
  (ms, sec, min, hour, mday, mon, year) := .Modelica.Utilities.System.getTime();
  .Modelica.Utilities.Streams.print("ms:" + String(ms) + "\n");
  .Modelica.Utilities.Streams.print("sec:" + String(sec) + "\n");
  .Modelica.Utilities.Streams.print("min:" + String(min) + "\n");
  .Modelica.Utilities.Streams.print("hour:" + String(hour) + "\n");
  .Modelica.Utilities.Streams.print("mday:" + String(mday) + "\n");
  .Modelica.Utilities.Streams.print("mon:" + String(mon) + "\n");
  .Modelica.Utilities.Streams.print("year:" + String(year) + "\n");
end GetTime;
