[boost] [date_time] Constructing ptime object from ISO 8601 compliant strings

A variation on this question was asked by Allen Cronce back in May, but I didn't see any answer posted.

The Posix Time description begins: "Defines a non-adjusted time system..."

I assume that this means it is not adjusted for time zone?

I need to construct ptimes from ISO 8601 compliant strings that may contain time zone information, such as this:
"2010-08-17 12:34:56-07:00"

If I constructed a ptime using this string, then used to_iso_string() to convert it to a string, I would expect to see "2010-08-17T19:34:56", but I don't. Rather, what I see is "2010-08-17T12:34:56" because the time zone portion of the string was ignored.

Does anyone have a suggestion for dealing with this situation? I have some ideas, but would be interested to hear what others have done.

Thanks,
Rush
