one hour shift when downloading with different timezones about qdownload HOT 2 CLOSED

I looked at the CSV output files from qdownload you provided with EST and UTC and they have a 4 hour difference, and it seems that this is the correct time zone offset for EST at that date: https://www.timeanddate.com/worldclock/converter.html?iso=20210517T080000&p1=179&p2=tz_gmt

Maybe the compare code use the wrong time zone?

You're right. My mistake was to use pytz.timezone('EST') instead of pytz.timezone('America/New_York') which contains DST (daylight saving transitions) information, whereas EST doesn't.
Changing the code to that timezone produces correct results.
