Concatenate files by date

[babelproofreader]

I have separate text files that consist of a date column followed by columns
of relevant data and I would like to load them and concatenate them into one
file that has the date column and then all the relevant data from the
following columns from the separate files. The date columns will
occasionally have missing/different dates so I'd like the date columns to be
merged whilst preserving the correct date stamps for the rows/columns of the
concatenated data.

A simple example:

File A
14/06/2016, 1, 2, 3
16/06/2016, 4, 5, 6

File B
15/06/2016, 7, 8, 9
17/06/2016, 10, 11, 12

should be merged to

File C
14/06/2016, 1, 2, 3
15/06/2016,  ,  ,  , 7, 8, 9
16/06/2016,4, 5, 6,  ,  ,  
17/06/2016,  ,  ,  , 10, 11, 12 

Can this be done in Octave, and if so, what is the Octave syntax?
