Caching the time zone value locally

Overview

Previously, the standard kernel cached all confstr values in libc, and procnto sent an event each every time a confstr value changed. Now, time zone caching provides you with the ability to cache the value locally, rather than having to incur the expense of retrieving it from procnto every time.

Configuration

You can set this variable at boot time by specifying a desired value in the rr_interval_mul field of the struct called qtime_entry when it's added to the system page. Typically, this code is included in the init_qtime() function.
