Less different than you might think, I'm afraid.
If you connect to a server that supports datetimeoffset with TDS 7.2,
you're using a protocol for which no datetimeoffset datatype is
defined. On your behalf, the server provides the data as a string,
which you see as VARCHAR. That's what's known as backwards
There are good reasons to update db-lib to support the new
datatypes, which after all are not so new anymore. What is lacking
someone with time and interest.
