Thanks for the solution. Sorry for the slow reply - I wanted to try it out,

Ah yes! Thank you, Greg!
I come from the Matlab world and am not very experienced with object
oriented program, but I was suspecting it was something like that.
I think I found a true bug in the way datetime objects work in db queries,
though -- I will post under a new subject heading.
Doing database queries on datetime.datetime fields seems broken. Here's an
example:
I have a database with a table 'transEntry' which includes a 'datetime'
field:
db.define_table('itemEntry',
* Field('dateTime','datetime'),*
Field('upc', 'string'),
Field('description',
Cut and paste, sorry!

Apologies again - all typos. The first query was built by typing (no longer
in my ipython history), and full of mistakes.
The proper way to do this is to create a simple sample that everyone can
replicate (too tired late last night to do so..).
Will do so now, constrained by work
I think you are right, Anthony!
In the original query, first_search (or gar with), first_search[270] is the
first entry on the new date!!!
(and also first_search[269] is the same entry as broken_query[269], so the
search results are the same up to that point).

I wasn't clear in my post : It's not a web app, I'm using DAL as part of a

I think I have figured it out, with the help of a python expert at work.

When creating my real database (not the toy example), I read raw date and
time data as an isoformat string, and relied on DAL/web2py to convert. But
