This uses the register_dataarray_accessor to add attributes similar to those in pandastimeseries which let the users quickly access datetime fields from an underlying array of datetime-like values. The referenced issue (#358) also asks about adding similar accessors for.str`, but this is a more complex topic - I think a compelling use-case would help in figuring out what the critical functionality is

Virtual time fields

Presumably this could be used to augment Dataset._get_virtual_variable(). A season field would need to be added as a special field to the accessor.
