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.
