DEF_GARBAGE_COLLECT_INTERVAL is 1440 seconds

In Lib/util.php I find

// Default window for Garbage Collection

define("DEF_GARBAGE_COLLECT_INTERVAL", 1440); 

The units are seconds, and 1440 seconds is 24 minutes, which does not seem correct.

The default interval was probably supposed to be 24 hours, which is 86400 seconds.
