Then it uses the astimezone function to adjust the time according to the requested time zone. It's the exact purpose of fromutc function:. Whereas the code below converts the current UTC time to a timezone aware datetime which is not necessarily current.

The timezone is just appended into the UTC time value. May I recommend to use arrow? If I understood the question:. Because utcnow method returns a naive object, so you have to convert the naive object into aware object.

Using replace method you can convert a naive object into aware object. Then you can use the astimezone method to create new datetime object in a different time zone.

Thank you. This library indeed looks as a good alternative to datetimehowever my project is big and I don't want to create more confusion by using another date-time library.

I will definitely consider using it in other projects. Another very easy way: Because utcnow method returns a naive object, so you have to convert the naive object into aware object.

It also solves the issue of ambiguous times at the end of daylight saving time, which you can read more about in the Python Library Reference datetime.

This library differs from the documented Python API for tzinfo implementations; if you want to create local wallclock times you need to use the localize method documented in this document. In addition, if you perform date arithmetic on local times that cross DST boundaries, the result may be in an incorrect timezone ie. A normalize method is provided to correct this. Unfortunately these issues cannot be resolved without modifying the Python datetime implementation see PEP This package can either be installed from a.

This library only supports two ways of building a localized time. The first is to use the localize method provided by the pytz library. This is used to localize a naive datetime datetime with no timezone information :. The second way of building a localized time is by converting an existing localized time using the standard astimezone method:.

The preferred way of dealing with times is to always work in UTC, converting to localtime only when generating output to be read by humans. This library also allows you to do date arithmetic using local times, although it is more complicated than working in UTC as you need to use the normalize method to handle daylight saving time and other timezone transitions.

Creating local times is also tricky, and the reason why working with local times is not recommended. Unfortunately, you cannot just pass a tzinfo argument when constructing a datetime see the next section for more details.

You can take shortcuts when dealing with the UTC side of timezone conversions. It is only used during DST transition ambiguous periods to resulve that ambiguity. AmbiguousTimeError exception. The major problem we have to deal with is that certain datetimes may occur twice in a year.

In fact, every instant between and occurs twice. Using the pytz custom syntax, the best you can do is make an educated guess:. For some applications, this does not matter. However, if you are trying to schedule meetings with people in different timezones or analyze log files it is not acceptable.

The best and simplest solution is to stick with using UTC. The pytz package encourages using UTC for internal timezone representation by including a special UTC implementation based on the standard Python reference implementation in the Python documentation.

The UTC timezone unpickles to be the same instance, and pickles to a smaller size than other pytz tzinfo instances.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Edit: the beast. You can build a timezone object for it with pytz like so:. If your target OS does this, you could make use of the file like so:. Your distribution may patch pytz module to use OS tz database instead of embed one e.
