Epoch Interpolation Raises Error

[matthewdahmer]

Updating the epoch for a model using the following code:

from xija import get_model_spec, ThermalModel
tstart = '2020:100:00:00:00'
tstop = '2022:100:00:00:00'
model_spec, version = get_model_spec.get_xija_model_spec('aca')
model = ThermalModel('aca', start=tstart, stop=tstop, model_spec=model_spec)
model.comp['aca0'].set_data(-10)
model.make()
model.comp['solarheat__aca0'].epoch = '2022:090'

Results in the following error:
