Converting a TSQL DateTimeOffset to UTC in Excel
/*
* if C2 contains a DateTimeOffset eg 2015-08-13 09:31:12.0000000 +01:00
* parse the date and time out and add them together
* then subtract the hours offset (which - in Excel time storage is hours/24)
* note that this ignores the minute-part of an offset (eg Venezuela)
