Convert EST Datetime to UTC Timestamp in Python 3-CodePudding

I'd like to know how to convert an EST Datetime string (e.g., '2020-02-02 09:30:00') to a UTC Timestamp with Python 3, without using external libraries such as pytz which gave me an inaccurate EST to UTC conversion.

CodePudding user response：

Converting time zones has been addressed here.

We just need fromisoformat for parsing.

The following will work with Python 3 from version 3.9 and up. If you're using Windows, make sure to run pip install tzdata to use ZoneInfo.

import datetime
from zoneinfo import ZoneInfo
estDatetime = datetime.datetime.fromisoformat('2020-02-02 09:30:00')
utcTimestamp = (
    date
    .replace(tzinfo=ZoneInfo("America/New_York"))
    .astimezone(ZoneInfo('UTC'))
    .timestamp()
)
