Is your database server's time offset 5 hours, or is the timezone itself just set to UTC-5? From what I can see, datetime
columns (as used in Cavalcade) are always stored as UTC, so it's only when we cast it in order to compare to now()
that it's an issue.
What I think you might be able to do is use per-connection timezones in both WordPress and Cavalcade-Runner to enforce the use of UTC. For Cavalcade, you should be able to do that with:
HM\Cavalcade\Runner::instance()->hooks->register( 'Runner.connect_to_db.connected', function ( $db ) {
$db->exec( 'SET time_zone = "+00:00"' );
} );
(You may want to do this on the WordPress side; the code for that is left as an exercise for the reader.)
Does that solve the issue for you? We could potentially look at building this in to Cavalcade, or changing NOW()
to use date( 'Y-m-d H:i:s' )
(although I'm unsure if the latter would affect query caching).

I did some local testing.
- I ran
SELECT NOW()
which returned2018-03-04 03:34:00
(the UTC time). - I then ran
INSERT INTO wp_cavalcade_jobs SET
site=1,
hook="fake",
args="a:0",
start="2018-03-04 13:34:00",
nextrun="2018-03-04 13:34:00"
- I ran
SELECT * FROM wp_cavalcade_jobs WHERE start < NOW()
and got 0 results - I ran
SET time_zone = "+10:00"
- I ran
SELECT NOW()
and got2018-03-04 13:34:00
(-ish) - I ran
SELECT * FROM wp_cavalcade_jobs WHERE start < NOW()
and got 1 result
So it appears that indeed the time_zone
variable does affect NOW()
but does not affect the datetime column, so setting the time_zone variable on connect should work correctly here.

@rmccue Thanks for this - you're right that time_zone
is the culprit. From what you've suggested here (which aligns with my tests), setting time_zone
in the runner seems to be the crux of the issue.

I've just run into this issue as well.
The proposed fix, adding:
HM\Cavalcade\Runner::instance()->hooks->register( 'Runner.connect_to_db.connected', function ( $db ) {
$db->exec( 'SET time_zone = "+00:00"' );
} );
didn't work for me. Adding:
$this->db->exec( 'SET time_zone = "+00:00"' );
after we create the PDO instance works though.

@discoinfiltrator These should be equivalent, so not sure what's happening there. You may need to check that your callback is actually being executed; might be that where you have that code is not being run?

Ah, my bad. I had added the code snippet incorrectly. Both are solving the problem for me.

Fantastic to hear.
I'd be happy to add this to the Cavalcade Runner code itself since it simply makes things consistent with no downsides for others, if anyone wants to open a PR :)

Sounds great. I've created: humanmade/Cavalcade-Runner#44
