They are just different ways of specifying when the learning rate starts to decrease. Originally we specified it as epochs, but later switched to hours with the idea that for very large datasets, you might not do more than one or two epochs. If you initialize with lr_hours, when you do the step_epoch() call (that's the name IIRC), you have to actually supply a number of hours rather than epochs.
