Description
I originally opened an issue with Freezegun:
spulec/freezegun#284
However, this appears to be a new quirk of Pandas 0.24's CustomBusinessDay class and its use of pandas._libs.tslibs.conversion.localize_pydatetime(). Other offset functions don't seem to be affected, for the ones I've tried.
Everything worked just fine with Pandas 0.23.4 and earlier, with the latest freezegun-0.3.11.
Code Sample, a copy-pastable example if possible
Test setup: Python 2.7 and 3.6 on OS X using freezegun-0.3.11 with pandas-0.24.2
import pytz
import pandas
from datetime import datetime
from pandas.tseries.offsets import (CustomBusinessDay, BusinessDay)
from freezegun import freeze_time
LOCAL_TZ = pytz.timezone('America/Los_Angeles')
@freeze_time(LOCAL_TZ.localize(datetime(2019, 3, 15, 0, 0, 0)))
def these_work():
pandas.Timestamp(datetime.now(LOCAL_TZ))
pandas.Timestamp(datetime.now(LOCAL_TZ)) + BusinessDay(n=1)
@freeze_time(LOCAL_TZ.localize(datetime(2019, 3, 15, 0, 0, 0)))
def this_fails():
pandas.Timestamp(datetime.now(LOCAL_TZ)) + CustomBusinessDay(n=1)

Expected Output
All of these should work equally well, including CustomBusinessDay.
