Please note that it is important to consider the value of this parameter in your connections and the corresponding settings of the QuickBooks Online. In many cases QuickBooks Online may display different values than set or returned via dotConnect for QuickBooks Online because of different time zone settings in your SqlShimConnection and in QuickBooks Online. For example, if you set UtcDates to true, and QuickBooks Online is configured to display datetime values in your local time, when you specify a datetime value in an INSERT or UPDATE statement, it is treated and sent to QuickBooks Online as a UTC value. When displaying this value in the QuickBooks Online interface, QuickBooks Online converts it to your local time, and thus displays a different value than the one that was specified in the INSERT or UPDATE statement.
The same is correct when selecting data. If UtcDates is set to true, and QuickBooks Online is configured to display datetime values in your local time, the date values returned via dotConnect for QuickBooks Online may differ from the values, displayed by QuickBooks Online. This happens because in this example QuickBooks Online convertsthe values to your local time when displaying them, and dotConnect for QuickBooks Online doesn't.
