Calculators I actually use.

[1][.][2][5][.][ENTER]
[2][.][1][2][.][+]

On RPN83P, this would be:

[{] [0] [,] [1] [,] [25] [ENTER]
[{] [0] [,] [2] [,] [12] [+]

The Duration object has 4 components {days, hours, minutes, seconds} which forces the initial 0.

If calculations with only 3 components (`hh:mm:ss`) are the most common, I suppose I could add a special case in the command line parser, to allow this to be entered as:

[1] [:] [25] [:] [ENTER]
[2] [:] [12] [:] [+]
