Scheduled posts aren't updated/saved in cron tasks

Hello.

Scheduled posts doesn’t work when Object cache is enabled.

My configuration:
– WordPress 4.3
– W3 Total Cache 0.9.4.1
– PHP 5.2.42

Test 1.
– Disable Object cache
– Schedule a new post publication in the future (id = 18019)
– Check cron task and search for the new post:
[1440367151] => Array(
[publish_future_post] => Array (
[af4934efbd7edbf10b44d27f4e27c5a2] => Array (
[schedule] =>
[args] => Array (
[0] => 18019
)
)
)
)
– Modify publication data and recheck cron tasks. Publishing timestamp changed to 1440370811 (later was 1440367151).

Test 2
– Enable object cache to disk
– Schedule a new post publication in the future (id = 18021)
– Check cron task and search for the future posts:
[1440370811] -> post 18019 is present, but post 18021 doesn’t appear in cron tasks.
Wordpress’ desktop shows both posts as scheduled, but only one is in the cron tasks.

Sometimes, when I edit a post’s publication date, the cron task remains the same: the timestamp doesn’t change. Other times it works.

Kind regards,
