enter manually a new gauged hydrograph after pressing the button +

when I tried to enter flow data, setting a constant time step 15 minutes, which my time series was, using "insert x rows":
it inserted an incremental time series like
0:00 > 0:15
0:15 > 0:30
0:30 > 1:00
even after removing the seconds from 00:00:00 to 00:00

but this does not happen using "paste x rows", after removing the seconds from 00:00:00 to 00:00, afaik

NB: I used EU Excel as input format so confusion about ,/. or "CRLF" is always a worry

I hope this helps others
