@FishermanJack: if you have Octave problems then you should ask on an Octave forum.

Sadly, there isn't such a forum for Octave (or none that I can find). I would suspect this wouldn't run correctly in Matlab either, as that first line doesn't fit the format.

Octave isn't Matlab despite it being similar and mostly syntax-similar.
While is OT here, from the error message I'd guess the problem is the format string isn't correct case for the month/hour/day fields...there's a difference between the old datenum and the new(er) datetime in who's upper- and who's lower- case; check the doc for "who's who in the zoo"...

The first entry is not parseable. The second others might have problems because of the spaces.

The first line 'yearmonthdayt [hh:mm]' cannot be parsed correctly. Try this:
datenum(cellstr(dt(2:end, :), 'yyyymmmddHH:MM')
Or do you have to consider the spaces?
datenum(cellstr(dt(2:end, :), 'yyyymmm dd HH:MM')
