You can use ntplib: from ntplib import NTPClient Now_ny = now_berlin.astimezone(ZoneInfo('America/New_York'))Īctually using ntp instead of the computer clock Now_berlin = datetime.now(ZoneInfo('Europe/Berlin')) Since python 3.9, the stdlib has the zoneinfo library, you can use this to convert between timezones.įor python < 3.9, you have to use a thirdparty library like dateutil. # convert back to datetime, specifying that the timestamp is in UTC # convert to unix, this will keep the utc timezone The correct solution in python 3 should be: from datetime import datetime, timezone Turns out this question was rather about how to convert to / from unix timestamps and datetimes. Getting correct, timezone aware datetimes and unix timestamps (No I have not done the statistical confidence interval posterior on the accuracy) It is then further feasible to write all the rest of my code such that all logic will assume UTC time. It is a feasible coding practice to write a "get UTC time now" code using all the information within the accepted answer, that is accurate to within a second or two. ![]() UPDATE: After accepting the provided answer it has become clear to me for my purposes, trusting my computer clock for a few seconds after updating my computer clock from a trusted source, then asking my computer clock for UTC time within those few seconds is good enough. TLDR I am looking for a reliable UTC api for python, and a way to prevent datetime from ever reading my computer clock again. # that would ask datetime library to attempt to read computer clock: #Trigger exception with new settings, when i accidentally write code #current_utc_datetime = current_utc_datetime_again ![]() #Transform back and forth to UTC Epoch time:Ĭurrent_utc_epoch = current_utc_datetime.timestamp()Ĭurrent_utc_datetime_again = (current_utc_epoch) #force datetime libaries to never read my computer clock:ĭatetime.some_settings_function( readcomputerclock = False/'Never' )Ĭurrent_utc_date_and_time_from_online = requests.get(.) #some api get requestĬurrent_utc_datetime = transform( current_utc_date_and_time_from_oneline ) The tools within the datetime.datetime objects are great, however it would be nice be able to flag some setting when importing the datetime library and prevent reading my computer clock entirely, to avoid any accidental clock badness issue.ĮXAMPLE OF CODE I AM LOOKING FOR: import datetime I keep finding myself accidentally being off 5 hours from EST, or off 1 hour from daylight savings when doing calculations. My use case is to do some time series analysis. I am trying to retool my code to entirely live in UTC time. I want to write the code assuming that if it runs from a computer with a bad clock, it still gets the correct time. Using '.utcnow()' or '.now()' both depend upon the accuracy of my computer clock. Does anyone have any tips to get the current UTC time, from online somewhere, and write some decent python code assuming my computer clock is always wrong? current_datetime = () #-> assume always wrongĬurrent_datetime = () #-> assume always wrong ![]()
