docs: def attime(self, **kwargs):
          r""" Returns a dictionary of latest observations at a user specified location for a specified time. Users must
          specify at least one geographic search parameter ('stid', 'state', 'country', 'county', 'radius', 'bbox', 'cwa',
          'nwsfirezone', 'gacc', or 'subgacc') to obtain observation data. Other parameters may also be included. See
          below for optional parameters. Also see the metadata() function for station IDs.
  
          Arguments:
          ----------
          attime: string, required
              Date and time in form of YYYYMMDDhhmm for which returned obs are closest. All times are UTC. e.g.
              attime='201504261800'
          within: string, required
              Can be a single number representing a time period before attime or two comma separated numbers representing
              a period before and after the attime e.g. attime='201306011800', within='30' would return the ob closest to
              attime within a 30 min period before or after attime.
          obtimezone: string, optional
              Set to either UTC or local. Sets timezone of obs. Default is UTC. e.g. obtimezone='local'
          showemptystations: string, optional
              Set to '1' to show stations even if no obs exist that match the time period. Stations without obs are
              omitted by default.
          stid: string, optional
              Single or comma separated list of MesoWest station IDs. e.g. stid='kden,kslc,wbb'
          county: string, optional
              County/parish/borough (US/Canada only), full name e.g. county='Larimer'
          state: string, optional
              US state, 2-letter ID e.g. state='CO'
          country: string, optional
              Single or comma separated list of abbreviated 2 or 3 character countries e.g. country='us,ca,mx'
          radius: string, optional
              Distance from a lat/lon pt or stid as [lat,lon,radius (mi)] or [stid, radius (mi)]. e.g. radius="-120,40,20"
          bbox: string, optional
              Stations within a [lon/lat] box in the order [lonmin,latmin,lonmax,latmax] e.g. bbox="-120,40,-119,41"
          cwa: string, optional
              NWS county warning area. See http://www.nws.noaa.gov/organization.php for CWA list. e.g. cwa='LOX'
          nwsfirezone: string, optional
              NWS fire zones. See http://www.nws.noaa.gov/geodata/catalog/wsom/html/firezone.htm for a shapefile
              containing the full list of zones. e.g. nwsfirezone='LOX241'
          gacc: string, optional
              Name of Geographic Area Coordination Center e.g. gacc='EBCC' See http://gacc.nifc.gov/ for a list of GACCs.
          subgacc: string, optional
              Name of Sub GACC e.g. subgacc='EB07'
          vars: string, optional
              Single or comma separated list of sensor variables. Will return all stations that match one of provided
              variables. Useful for filtering all stations that sense only certain vars. Do not request vars twice in
              the query. e.g. vars='wind_speed,pressure' Use the variables function to see a list of sensor vars.
          status: string, optional
              A value of either active or inactive returns stations currently set as active or inactive in the archive.
              Omitting this param returns all stations. e.g. status='active'
          units: string, optional
              String or set of strings and pipes separated by commas. Default is metric units. Set units='ENGLISH' for
              FREEDOM UNITS ;) Valid  other combinations are as follows: temp|C, temp|F, temp|K; speed|mps, speed|mph,
              speed|kph, speed|kts; pres|pa, pres|mb; height|m, height|ft; precip|mm, precip|cm, precip|in; alti|pa,
              alti|inhg. e.g. units='temp|F,speed|kph,metric'
          groupby: string, optional
              Results can be grouped by key words: state, county, country, cwa, nwszone, mwsfirezone, gacc, subgacc
              e.g. groupby='state'
          timeformat: string, optional
              A python format string for returning customized date-time groups for observation times. Can include
              characters. e.g. timeformat='%m/%d/%Y at %H:%M'
  
          Returns:
          --------
              Dictionary of observations around a specific time.
  
          Raises:
          -------
              None.
