Climatology is broken

[matt-long]

I am getting errors on this line:

esmlab/esmlab/core.py

Line 466 in bbad55c

time_data = computed_dset[self.tb_name] - computed_dset[self.tb_name][0, 0]

The computed_dset does not have the time_bound variable. This is being stripped out somewhere in the compute_time_var method.

[matt-long]

This issue arises when time_bound is a coordinate, which results from reading data in via intake_esm. Should we be treating this case, at least in notifying the user?
