Implement time filter '&time=latest'

[P3nny]

Time filter '&time=last' is ignored or errors

get_df('?data=11111:FLC006&level=1&layout=region&time=last')

Returns table with all years

get_df('?data=11111:FLC006&level=2&layout=region&time=last')

Works:
get_df('?region=DG&data=11111%3AGEM001&time=2017')

Errors (last available year is not working):
get_df('?region=DG&data=11111%3AGEM001&time=2018')

Is ignored:
get_df('?region=DG&data=11111%3AGEM001&time=last')

Not working:
get_df('?regions=all&data=11111%3AGEM001&nuts=1&time=2017&labels=both')

Some years seem to be broken:

• Area
  get_df('?regions=all&data=11111%3AFLC006&time=2017&labels=name')

500
get_df('?regions=all&data=11111%3AFLC006&time=2018&labels=name')
