Input (New York Time in string format) = '2024-11-01 13:00:00' Output (UTC Time in string format) = '2024-11-01 17:00:00'
Parse the time. It won't be "time zone aware", so apply local time zone, convert to UTC and format again: import datetime as dt import zoneinfo as zi zone = zi.ZoneInfo('America/New_York') fmt = '%Y-%m-%d %H:%M:%S' s = '2024-11-01 13:00:00' print(s) # parse the time and apply the local time zone nyt = dt.datetime.strptime(s, fmt).replace(tzinfo=zone) # convert to UTC and format string utc = nyt.astimezone(dt.UTC).strftime(fmt) print(utc)  Output: 2024-11-01 13:00:00 2024-11-01 17:00:00
