Timezone issue

[Kayden-lolasery]

Describe the bug

UTC to UTC + 8 is not working as intended (it is an hour behind)

How to Reproduce

import pytz

# argus_path is a s3 path
zzzzz = wr.s3.describe_objects(argus_path, last_modified_begin=dt(2024, 7, 20, 19, 0, tzinfo=pytz.timezone('Asia/Singapore')))
print([zzzzz[i]['LastModified'] +timedelta(hours=8) for i in zzzzz])

Expected behavior

i would expect last_modified_begin=dt(2024, 7, 20, 19, 0, tzinfo=pytz.timezone('Asia/Singapore')) to give me everything including and after 7pm but it doesnt.

seems like pytz library changed in behaviour ... perhaps it does some DST during its conversion.
specifying a datetime pytz's timezone object results in:
<DstTzInfo 'Asia/Singapore' LMT+6:55:00 STD>
while the dt.now() timezone object results in:
<DstTzInfo 'Asia/Singapore' +08+8:00:00 STD>

I'll use zoneinfo.ZoneInfo instead.
