Timezone conversion

Don't know why this code doesn't work. Please hint why .

aware.py
import datetime

naive = datetime.datetime(2015, 10, 21, 4, 29)

pacific = datetime.timezone(datetime.timedelta(hours=-8))

hill_valley = datetime.datetime(2015, 10, 21, 4, 29, tzinfo=pacific)

new_tz = datetime.timezone(datetime.timedelta(hours=1))

paris = datetime.datetime(2015, 10, 21, 4, 29, tzinfo=new_tz)

hill_valley.astimezone(new_tz)

import datetime

naive = datetime.datetime(2015, 10, 21, 4, 29)

pacific = datetime.timezone(datetime.timedelta(hours=-8))

hill_valley = naive.replace(tzinfo=pacific)

new_tz = datetime.timezone(datetime.timedelta(hours=1))

paris = datetime.datetime(2015, 10, 21, 4, 29, tzinfo=new_tz)

hill_valley = hill_valley.astimezone(new_tz)

I corrected the conversion of hill_valley to new_tz. but now I get the error message that task 1 is no longer passing. Why not? Please advice.
