Datetime bug

[MPavicevic]

When time series input csv has more years then one and no leap year is present new year specified in the config file overwrites all days in csv file to a new year. This results in an error in last line of function: load_time_series(config,path,header='infer'):

return data.reindex(config['idx_long'], method='nearest').fillna(method='bfill')

I will work on this! This is just a reminder so that i don't forget!
