Timezone Conversion

For details, see the official documentation.

# Jodoo uses UTC as the standard timezone for Date&Time values. As China is in UTC+8 timezone, the string 
# "2020-04-14T07:32:22.000Z" in Jodoo will be eight hours behind the local time, which is '2020-04-14 15:32:22'

# You can use pytz to convert between timezones.

import datetime
import pytz

# Steps for timezone conversion
# UTC str -> UTC datetime -> Convert timezone -> Local datetime -> Local str
