I do believe that date/time support has been incorporated into MITAB and
the OGR bindings in recent versions of OGR.  If not it might be worth
filing a ticket on this.  Does the OGR FDO provider support date/time fields?
They are a relatively recent addition to OGR.

Is this an improvement that can be done right in the FDO OGR provider?

Overall, I'd prefer to see the requirement for good mapinfo support drive
improvements to the FDO OGR provider (and perhaps OGR/MITAB)
rather than do something really custom.
