How can I convert a Sql Server 2008 DateTimeOffset to a DateTime

Question

I'm hoping to convert a table which has a DATETIMEOFFSET field, down to a DATETIME field BUT recalculates the time by taking notice of the offset. This, in effect, converts the value to UTC.

eg.

CreatedOn: 2008-12-19 17:30:09.0000000 +11:00

that will get converted to

CreatedOn: 2008-12-19 06:30:09.0000000

or

CreatedOn: 2008-12-19 06:30:09.0000000 + 00:00 -- that's a `DATETIMEOFFSET`, but `UTC`.

Cheers :)
