I have a datetime like this Thu Jun 02 11:56:53 CDT 2011
I tried to convert it to datetime object using the code below
from dateutil import parser
timestamp = parser.parse("Thu Jun 02 11:56:53 CDT 2011")
But I get this warning
UnknownTimezoneWarning: tzname CDT identified but not understood.
Pass `tzinfos` argument in order to correctly return a timezone-aware datetime.
In a future version, this raise an exception.
category=UnknownTimezoneWarning)
There is no warning when I use UTC instead of CDT.
Can I use tzinfos to fix this ?

collect a timezone info from https://www.timeanddate.com/time/zones/ as @pLOPeGG answer, you can use as demo
#!/usr/bin/env python
# encoding:utf-8
from dateutil import parser

timestamp = parser.parse("Thu Jun 02 11:56:53 CDT 2011", tzinfos={"CDT": -5*3600})
Short answer, without using tzinfos, replace CDT with its UTC equivalent:
In [15]: from dateutil import parser
...: timestamp = parser.parse("Thu Jun 02 11:56:53 UTC-5 2011")
...:
...:
In [16]: timestamp
Out[16]: datetime.datetime(2011, 6, 2, 11, 56, 53, tzinfo=tzoffset(None, 18000))
You can use tzinfos, it must be a dict where keys are the unknows timezones and values are either string UTC format (UTC-5 for example) or number of seconds to offset, here is the doc:
TZINFOS
Additional time zone names / aliases which may be present in the string. This argument maps time zone names (and optionally offsets from those time zones) to time zones. This parameter can be a dictionary with timezone aliases mapping time zone names to time zones or a function taking two parameters (tzname and tzoffset) and returning a time zone. The timezones to which the names are mapped can be an integer offset from UTC in seconds or a tzinfo object. This parameter is ignored if ignoretz is set.
I tried with both methods and compared
timestamp = parser.parse("Thu Jun 02 11:56:53 CDT 2011", tzinfos={"CDT": -5*3600})
timestamp2 = parser.parse("Thu Jun 02 11:56:53 CDT 2011", tzinfos={"CDT": "UTC-5"})
timestamp3 = parser.parse("Thu Jun 02 11:56:53 UTC-0500 2011")
and it prints
2011-06-02 11:56:53-05:00
2011-06-02 11:56:53-05:00
2011-06-02 11:56:53+05:00
it seems like you have to inverse the sign when using tzinfos (correct me, it might be the inverse thing to do)
