3. **Should I install pytz?**
|

|

Yes. Django has a policy of not requiring external dependencies, and for
|
||||
this reason pytz_ is optional. However, it's much safer to install it.
|
||||
|
||||
As soon as you activate time zone support, Django needs a definition of the
|
||||
default time zone. When pytz is available, Django loads this definition
|
||||
from the `tz database`_. This is the most accurate solution. Otherwise, it
|
||||
relies on the difference between local time and UTC, as reported by the
|
||||
operating system, to compute conversions. This is less reliable, especially
|
||||
around DST transitions.
|

Furthermore, if you want to support users in more than one time zone, pytz
