for timerange in np.array_split(sorted(set(t.getcol('TIME'))), round(hours)):

I think that by splitting this way the regular structure of (time[i]-time[i+1])=constant is destroyed at the boundaries of the split. That means that after combining the ms again in time (which one sometimes wants), the time axis has become irregular. An easy solution I think would be to split with taql in integer units of timesteps. A simple example to split select time steps, say from 120 to 140 with taql is:

taql 'select from bla.MS where TIME in (select distinct TIME from bla.MS offset 120 limit 20) giving bla-subset.MS as plain'
