Add ability to clamp or threshold by time.
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
I have a user that has multiple runs that overlap in time. He wants to use the first 3/4 of the first run, ignoring the rest of the time steps, and the last 3/4 of the second run. (These two runs do not represent exactly the same time - for instance the first dataset goes from time 0 to 4 seconds, and the second goes from 2 to 6 seconds. So, he wants 0-3 from the first dataset, and 3-6 seconds from the second dataset.
