There are problems with Delphi date conversion routines and others (Rxlib for
one, and either InfoPower or TurboPower was another, I forget exactly), when
your PC has a date format like "d-mmm-yyyy". The single "d" means 'suppress
the zero if the day is less than 10', but the conversion routines I traced in
Rxlib tried to match up the string date with the format string CHARACTER FOR
CHARACTER, which don't work so well after the 10th of the month 'cause the date
is longer than the format ...
Of course it just so happens that I kinda prefer that date format, so I have had
some awkward problems with date conversions before. I think it may have been
compounded by using "-" for the delimiter, instead of "/". Unfortunately I
don't have a current example to hand so I can't be more specific.
Was the system default date format (probably the short one) on that PC different
to the others?

PS sorry about shouting!

Why don't you just set the TDateTime to zero?
