I understand that the timezone of result from rdp.get_historical_price_summaries() is UTC and I need to input UTC timezone to request. I wonder that how to use start, end and count. I try to retrieve 30Min data for 30APR2021. Please refer to the see below, I put start as '2021-04-30 01:00:00', but I got data start from 2021-04-29 17:04:00.
Also, when I use start ='2021-04-30 01:00:00' and count = 20, I get data start from 2021-05-03 00:33:00. Please advise,
Thank you very much.
