When a timezone produces an out-of-bounds utc offset, the resulting exception always claims that the offset was 1440, rather than whatever it was. Example:
from datetime import timedelta, datetime, tzinfo
class X(tzinfo):
 def utcoffset(self, time):
 return timedelta(days=2)
datetime.now(tz=X())

Is 3.3 message better?
>>> datetime.now(tz=X())
Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
ValueError: offset must be a timedelta strictly between -timedelta(hours=24) and timedelta(hours=24).
In 2.7, the message is indeed misleading:
>>> datetime.now(tz=X())
Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
ValueError: tzinfo.utcoffset() returned 1440; must be in -1439 .. 1439
I am not sure fixing this in 2.x is worth the trouble, but I would consider improving the message in 3.x by adding information about the actual offset. I vaguely remember that there was a reason for leaving that info out in 3.x.

Does anyone still care about this issue? I think the error message in 3.2 is good enough and fixing this in 2.x is not worth the trouble. I am inclined to close this as "won't fix".

Fixed in changeset a7237f157625.
