Timezone not being parsed on some machines

[ttecles]

Hi,

I am running the ciso8601 parse_datetime function in different hosts with the same python version 3.9.18 and the same ciso8601 version 1.0.8 but I am seeing some inconsistencies.

In Linux hostname1 5.15.0-125-generic #135-Ubuntu SMP Fri Sep 27 13:53:58 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux host I get the following:

Python 3.9.18 (main, Aug 25 2023, 13:20:14) 
[GCC 11.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from ciso8601 import parse_datetime
>>> parse_datetime("2024-01-01T00:00:00+01:00")
datetime.datetime(2024, 1, 1, 0, 0, tzinfo=pytz.FixedOffset(60))

But in a Linux hostname2 6.11.0-19-generic #19~24.04.1-Ubuntu SMP PREEMPT_DYNAMIC Mon Feb 17 11:51:52 UTC 2 x86_64 x86_64 x86_64 GNU/Linux host:

Python 3.9.18 (main, Mar  6 2025, 15:28:01) 
[GCC 13.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from ciso8601 import parse_datetime
>>> parse_datetime("2024-01-01T00:00:00+01:00")
datetime.datetime(2024, 1, 1, 0, 0)

I get no tzinfo.
