Find Photos by capture time?

Question

I'm having a bit of trouble finding photos by capture time. It seems that catalog:findPhotos() works on captureDate, but not time.
I have a photo that I know the date is 2010-11-28 02:10:00 - I can do a getAllPhotos() and dump the capture time to verify.
This works:
local catalog = import 'LrApplication'.activeCatalog()
    local foundPhotos = catalog:findPhotos {
         searchDesc = {
                 criteria = "captureTime",
                 operation = "in",
                 value = "2010-11-27",
                 value2 = "2010-11-29",
This doesn't:
         searchDesc = {
                  criteria = "captureTime",
                  operation = "=",
                  value = "2010-11-28",
nor does:
                 value = "2010-11-28T02:10:00",
or does any other variant I've tried, and I've tried all the sqllite query formats for date time. In fact, I can't find any solution that a "=" criteria works for captureTime.
This is pretty big for my plugin... can anyone help? Please?

Still no luck.
Here's what I'm trying (with a different image, so the dates are now different than my original post):
    local foundPhotos = catalog:findPhotos {
         searchDesc = {
                 criteria = "camera", -- searches Camera Model
                 operation = "==",
                 value = "Canon EOS 7D",
                 criteria = "captureTime",
                 operation = "==",
                 value = 294962994,
             combine = "intersect",
for x = 1, #foundPhotos do
        local photo = foundPhotos[x];
        log("\traw dateTimeOriginal: " .. (photo:getRawMetadata("dateTimeOriginal") or null));
end
if I run this, I get 9 entries. here's the last 3:
[1676] ErisApp TRACE  raw dateTimeOriginal: 299806234
[1676] ErisApp TRACE  raw dateTimeOriginal: 294962994
[1676] ErisApp TRACE  raw dateTimeOriginal: 294962966
Camera model does match, so I know at least part of the search critiera is working correctly.
Surely I'm doing something wrong?
Thanks for your help!
