Yes. But not right now.
We have a number of routines in the grid.py library:
timeStepDifference
timeStepSum
minOverTime
etc.
We just don't have any that do a difference from a fixed time step.
I'll create a routine for that tomorrow.
But, can you brainstorm other related functions you might want to use that
deal with one field and multiple times?
