Glad my observations helped, but I'm not especially familiar with
TDateTimePicker.   I was simply curious about the behaviour you described so
had a quick (2-3 mins, at the most) look at the VCL source for the control,
looking for code that changed the internal fDateTime value directly or
indirectly and found the behaviours that I then described.

 

Use the source, Luke.

The source will be with you.  Always.

etc etc

 

I then deserialised a TConsciousnessStream as I considered how I'd go about
mitigating that behaviour if I were writing code affected by it.

It looks like D5 does not have DateOf, but the Trunc function works fine
(with a comment of why).   Thanks for Jolyon for the description of the
oddities of this control - it looks like he has been bitten by this oddity
and knows it well!

DateOf() is nothing more than a wrapper for Trunc(TheDate)  but I like to
use it becuase then you know what its doing :-)  BTW TimeOf(TheDate) returns
only the time portion of a date/time  and is just a wrapper for
Frac(TheDate). Once agai I use this so I know what the code is doing.
