You can see this in [this discussion](https://github.com/patwmcnamara/GADS11-NYC-Summer2014/issues/50). It is possible however, to change the scale so that it shows human readable dates, but it's quite cumbersome and I had to try many times before finding a working solution [here](https://stackoverflow.com/questions/42749741/matplotlib-colorbar-change-ticks-labels-and-locators).\r\n\r\nI think that the colorbar, in these cases, should have a readable scale by default, and matplotlib already uses it when one of the axes of a plot is datetime, so I think it should be natural to adopt it also for colorbars.
