When choosing All Marketplaces we are using the default currency code of GBP for the UK Market. We are also converting any currency with the code of EUR to GBP based on the order date using the exchange rates provided by the European Central Bank. These rates are published at about 3pm CET daily. Please note we are not tracking hour exchange rates.

As for the time stamp, we are using BDT conversions during daylight savings and GMT otherwise. During our research we found this to be the best approach and most consistent with how Amazon is coding the time stamps for these orders.
