time needs to be a dimension in NetCDF

[faronium]

I've noted when working with NetCDFs from the YNWT data portal that time is incorporated as a data variable rather than a dimension of the NetCDF. Here's the output of ncinfo on a file:

root group (NETCDF3_64BIT_OFFSET data model, file format NETCDF3):
elevation: 242.5
name: CRMP/ECCC
station_id: 2202349
latitude: 67.0667
contact: Faron Anslow fanslow@uvic.ca
longitude: -121.1
version: 0.2
owner: PCIC
station_name: HALDANE RIVER
history: Created dynamically by the Pydap SQL handler, the Pydap PCIC SQL handler, and the PCIC/CRMP database
network: ECCC
dimensions(sizes): station_observations(24045)
variables(dimensions): float64 Temperature(station_observations), float64 Dir_of_Max_Gust(station_observations), float64 Humidity(station_observations), float64 daily_snow_24hr(station_observations), float64 Min_Temp(station_observations), float64 Dew_Point_Temp_degC(station_observations), float64 Wind_Speed(station_observations), float64 Total_Rain(station_observations), float64 Snow_on_Grnd(station_observations), float64 Mean_Temp(station_observations), float64 Wind_direction(station_observations), float32 time(station_observations), float64 Total_Precipitation(station_observations), float64 Spd_of_Max_Gust(station_observations), float64 Max_Temp(station_observations)

and a print of another dataset as an xarray object:

I don't think this is a strict requirement of CF conventions, but having a time dimension is useful.

Hopefully this is a quick/easy fix and sorry for the rapidfire issues.
