The clock_t type in OpenSolaris is long (int64_t on amd64). On FreeBSD clock_t is int32_t. The clock_t type is used in several places in the ZFS code to store system uptime in milliseconds ("seconds * hz"). With hz=1000 we have a 32-bit integer overflow in 24 days, 20 hours, 31 minutes and 23.648 seconds. This has a user reported negative impact on l2arc_feed_thread() and may cause unexpected results from other functions using clock_t.
