Convert between local time to UTC time in Python

To convert between local time and UTC time in Python, you can use the pytz library, which provides comprehensive timezone support. If you don't have the library installed, you can install it using pip:

pip install pytz

Here's an example of converting a local time to UTC time and vice versa using the pytz library:

from datetime import datetime
import pytz

# Create a datetime object representing the local time
local_dt = datetime.now()

# Set the timezone for the local time
local_tz = pytz.timezone("America/New_York")  # Replace with your local timezone
localized_dt = local_tz.localize(local_dt)

# Convert the local time to UTC time
utc_dt = localized_dt.astimezone(pytz.utc)
print(f"Local time: {localized_dt}")
print(f"UTC time: {utc_dt}")

# Convert the UTC time back to local time
converted_local_dt = utc_dt.astimezone(local_tz)
print(f"Converted local time: {converted_local_dt}")

In this example, we first create a datetime object representing the current local time. Then, we set the timezone for the local time using the timezone() function from the pytz library. After that, we use the localize() method to attach the timezone information to the datetime object.

To convert the local time to UTC time, we use the astimezone() method with pytz.utc as the argument. This will return a new datetime object with the time converted to UTC.

Finally, to convert the UTC time back to local time, we use the astimezone() method again with the local timezone as the argument.

Note: Make sure to replace "America/New_York" with the appropriate timezone for your local time.

Python convert local time to UTC:

from datetime import datetime, timezone

local_time = datetime.now()
utc_time = local_time.astimezone(timezone.utc)
print(utc_time)

Convert UTC to local time in Python:

from datetime import datetime, timezone

utc_time = datetime.utcnow()
local_time = utc_time.astimezone(timezone.utc).astimezone()
print(local_time)

Python pytz library for timezone conversion:

from datetime import datetime
import pytz

local_time = datetime.now(pytz.timezone('America/New_York'))
utc_time = local_time.astimezone(pytz.utc)
print(utc_time)

Convert string to datetime with timezone in Python:

from datetime import datetime
import pytz

date_string = "2023-01-01T12:00:00"
datetime_with_tz = datetime.fromisoformat(date_string).replace(tzinfo=pytz.timezone('America/New_York'))
print(datetime_with_tz)

Convert timestamp to UTC time in Python:

from datetime import datetime, timezone

timestamp = 1609459200  # Example timestamp
utc_time = datetime.utcfromtimestamp(timestamp).replace(tzinfo=timezone.utc)
print(utc_time)

Convert ISO 8601 string to UTC time in Python:

from datetime import datetime, timezone

iso_string = "2023-01-01T12:00:00Z"
utc_time = datetime.fromisoformat(iso_string).replace(tzinfo=timezone.utc)
print(utc_time)

Convert datetime to timestamp in UTC in Python:

from datetime import datetime, timezone

utc_time = datetime.now(timezone.utc)
timestamp = int(utc_time.timestamp())
print(timestamp)

Using dateutil.tz for timezone conversion in Python:

from datetime import datetime
from dateutil import tz

local_time = datetime.now(tz.gettz('America/New_York'))
utc_time = local_time.astimezone(tz.tzutc())
print(utc_time)

Python arrow library for datetime with timezone:

import arrow

local_time = arrow.now('America/New_York')
utc_time = local_time.to('UTC')
print(utc_time)

Convert between UTC and local time with pytz in Python:

from datetime import datetime
import pytz

local_time = datetime.now(pytz.timezone('America/New_York'))
utc_time = local_time.astimezone(pytz.utc)
print(utc_time)

# Convert back to local time
converted_local_time = utc_time.astimezone(pytz.timezone('America/New_York'))
print(converted_local_time)

Python strftime for timezone-aware datetime:

from datetime import datetime
import pytz

local_time = datetime.now(pytz.timezone('America/New_York'))
formatted_string = local_time.strftime("%Y-%m-%d %H:%M:%S %Z")
print(formatted_string)

UTC to local time conversion with timedelta in Python:

from datetime import datetime, timedelta, timezone

utc_time = datetime.utcnow().replace(tzinfo=timezone.utc)
local_time = utc_time - timedelta(hours=5)  # Adjust based on the timezone offset
print(local_time)

Convert datetime to UTC timestamp in Python:

from datetime import datetime, timezone

local_time = datetime.now()
utc_timestamp = int(local_time.replace(tzinfo=timezone.utc).timestamp())
print(utc_timestamp)
