Those unix_time values don't seem to correspond to the dates you have.

| NOW()               | UNIX_TIMESTAMP(NOW()) |
| 2010-10-04 13:18:08 |            1286223488 |

1286223428 vs 12862162510269684

Your value has far too many digits. That's also beyond the range of a 32 bit int.  Are you

I suspect the issues is due because of something different about the values you have in
your table.  Try posting the SHOW CREATE TABLE table \G output, and a sample INSERT
statement to populate the table.  That way someone can try to reproduce the behavior
you're seeing.

Subject: update and times

hi all...

i'm doing tests with a table that gets updated based on random unix
times it contains. there is a column that has a bunch or random times
that look like:

 | date_time              | unix_time            |
 | 2010-10-01 10:24:52 | 12859430921341418 |
 | 2010-10-01 21:18:13 | 12859822937839442 |
 | 2010-10-01 16:08:00 | 12859636809115039 |
 | 2010-10-01 19:47:43 | 12859768633824661 |
 | 2010-10-01 16:48:30 | 12859661104829142 |
 | 2010-10-01 15:25:37 | 12859611374324533 |
 | 2010-10-01 12:27:28 | 12859504483288358 |

what i'm trying to do is update the column only of one of those times
isn't yet passed. and it works. except sometimes...

like these 2 unix times:

this was in the table under unix time: 12862162385941345...

this 12862162510269684 got passed in the update command as in:

update the_table set updated = 1 where unix_time < 12862162510269684
limit 1;

executing this query didn't update the record.
