UTC

# Import relevant classes
from datetime import datetime, timedelta, timezone

# US Eastern Standard time zone
ET = timezone(timedelta(hours=-5))

# Timezone-aware datetime
dt = datetime(2017, 12, 30, 15, 9, 3, tzinfo = ET)

print(dt)

2017-12-30 15:09:03-05:00

UTC

# India Standard time zone
IST = timezone(timedelta(hours=5, minutes=30))

# Convert to IST
print(dt.astimezone(IST))

2017-12-31 01:39:03+05:30

Adjusting timezone vs changing tzinfo

print(dt)

2017-12-30 15:09:03-05:00

print(dt.replace(tzinfo=timezone.utc))

2017-12-30 15:09:03+00:00

# Change original to match UTC
print(dt.astimezone(timezone.utc))

2017-12-30 20:09:03+00:00
