> Hi,

expiration_date

> We then tries to get all published objects that have not yet been
archived:

> now=_.DateTime()
> Service.searchResults(
>      effective_date =now, effective_date_usage='range:max'
>      , expiration_date =now, expiration_date_usage='range:min'

correctly.

not

> Now using now2 in:

>      effective_date =now, effective_date_usage='range:max'

> What I don't seem to understand is that DateTime() and
> DateTime(DateTime().Date) gets so different results.
