Converts this TimeOfDay to a string with the format HH:MM:SS. If writer is set, the resulting string will be written directly to it.

string toISOExtString() pure nothrow @safe const;

void toISOExtString(W) (
  ref W writer
) const
if (isOutputRange!(W, char));


writer A char accepting output range


A string when not using an output range; void otherwise.


writeln(TimeOfDay(0, 0, 0).toISOExtString()); // "00:00:00"
writeln(TimeOfDay(12, 30, 33).toISOExtString()); // "12:30:33"
