Yeah- this sort of thing /is/ fun, isn't it? :-) Frankly I don't think
that there's a "correct" solution (look as the vituperation surrounding
MS timezone handling) and the more info you store when the data is saved
the better since that gives you the option of going back and re-running
reports if somebody tells you the goalposts have moved. I store all data
in GMT with info in each record so that it's traceable, gross timezones
can obviously be handled easily in the query but the final application
of DST correction is handled in the client apps (written in Delphi but
using embedded scripting and interpolation).
