Time conversion

Specify a time lag (-6 hours) in the subroutine that generates the date and time format from the original “days of the year” and “hour” information.

        timestamp = dayofY_toTimeStamp(df,-6) 

def dayofY_toTimeStamp(df,deltt):

    newdate = pd.to_datetime(df.loc[:,'Year'].values*10000000+df.loc[:,'Day_of_Year'].values*10000+df.loc[:,'HrMin'], format='%Y%j%H%M') \
            + pd.Timedelta(hours=deltt)

    return newdate

Note

The time conversion does not include daylight savings time adjustment.
