Hi, I've enabled the Joomla cache with APC User Cache. I've set the cache time on the configuration to "15" (which according to the description, should be 15 minutes).

Unfortunately, Joomla seems to still use that number as seconds instead of minutes.

Having seen this I then changed the cache time to "300", cleared the cache and tried it again.

Now Joomla stores most of the cache for 300 seconds but there are still a lot of cached items with 15 seconds timeout.

Below are some screenshots of my joomla configuration and APCu status page.

Steps to reproduce the issue

Enable Joomla Cache (conservative/APC User Cache)
Set "Cache Time" to "15"

Expected result

Joomla stores the cache items with 15 minutes expiration (900 seconds)

Actual result

Joomla stores the cache items with 15 seconds expiration

System information (as much as possible)

debian 8.4
nginx 1.9.10
php-fpm 5.6.20
php-apcu 4.0.7
joomla 3.5.1

Additional comments

I've posted about this before on #8707 and according to that thread, this issue should have been resolved on a recent cache system rewrite so if anyone using apcu could try to reproduce and confirm if this is also happening to them it would be great.
