1. NOP Commerce version: 4.50.2
2. Expected behaviour: The numbers of orders listed in the two reports should match
3. Actual behaviour: Sales > Orders and Reports reflects server time, whereas Reports > Sales Summary uses UTC time (and also includes a line for the day before the selected start date if there were orders when the order date/time UTC was before midnight and server time was the next day.
Example:
In the UK we are now on summer time (UTC+1 hour) which is also the server time.
The CreatedOnUtc time on the Order table is UTC(+0) as expected.
Sales > Orders shows the summer time against each order, and when filtering on the Start and End dates, will include orders based on summer time.
However, Reports > Sales Summary uses the UTC time.
Therefore, when there are orders placed between UTC 23:00:00 and 23:59:59, there is a discrepancy in order numbers between the above two facilities because the orders are included/counted on different days.
In addition, in Reports > Sales Summary, when selecting a date range, if on the day before the "Start date" there were orders placed between UTC 23:00:00 and 23:59:59, the report will include a line for that date including the totals only for any late-night orders, when that date was not required.
E.g. in Reports > Sales Summary I ran a report with date range 20/06/2022 to 22/06/2022, but it also shows 4 orders on 19/06/2022 (all 4 were raised UTC 23:00:00-23:59:59 on that date - it has not counted other orders from earlier that day, so that day's figures are also incorrect).
Reports > Sales Summary should base its results on the server time as the orders page does this.
NB. In System > System Information, our "Server time zone" is "GMT Standard Time", and the "Server local time" and "Current user time" correctly reflects this (i.e. UTC+1), and "Coordinated Universal Time (UTC)" correctly shows the UTC time. In Configuration > Settings > Customer Settings, we are on UTC+00:00
