Comment 8 for bug 654030

You can't import directly the time interval data from the CSV import in data laboratory, but you have an easy way to convert a numerical column into the time interval. Import your time data as a DOUBLE or INT and look at this wiki tutorial: http://wiki.gephi.org/index.php/Import_Dynamic_Data#Tranform_existing_column_in_Time_Interval to know how to get the time interval from that.

On the tutorial you also have the method with importing slices from a GEXF file.

The fact you're properly importing a Time_INTERVAL column but it is not activated as the dynamic column could be improved, we could activate it by default is no other TIME_INTERVAL columns exists. It is currently not done, as it is not the default use-case.
