 =item $cf::UPTIME
-The timestamp of the server start (so not actually an uptime).
+The timestamp of the server start (so not actually an "uptime").
+=item $cf::SERVER_TICK
+An unsigned integer that starts at zero when the server is started and is
+incremented on every tick.
+=item $cf::NOW
+The (real) time of the last (current) server tick - updated before and
+after tick processing, so this is useful only as a rough "what time is it
+now" estimate.
+=item $cf::TICK
+The interval between each server tick, in seconds.
 =item $cf::RUNTIME
 The time this server has run, starts at 0 and is increased by $cf::TICK on
 every server tick.
 Various directories - "/etc", read-only install directory, perl-library
 directory, pod-directory, read-only maps directory, "/var", "/var/tmp",
 unique-items directory, player file directory, random maps directory and
 database environment.
-=item $cf::NOW
-The time of the last (current) server tick.
-=item $cf::TICK
-The interval between server ticks, in seconds.
 =item $cf::LOADAVG
 The current CPU load on the server (alpha-smoothed), as a value between 0
 (none) and 1 (overloaded), indicating how much time is spent on processing
 objects per tick. Healthy values are < 0.5.
 =item cf::wait_for_tick, cf::wait_for_tick_begin
 These are functions that inhibit the current coroutine one tick. cf::wait_for_tick_begin only
 returns directly I<after> the tick processing (and consequently, can only wake one thread
 per tick), while cf::wait_for_tick wakes up all waiters after tick processing.
+Note that cf::Wait_for_tick will immediately return when the server is not
+ticking, making it suitable for small pauses in threads that need to run
+when the server is paused. If that is not applicable (i.e. you I<really>
+want to wait, use C<$cf::WAIT_FOR_TICK>).
+=item $cf::WAIT_FOR_TICK
+Note that C<cf::wait_for_tick> is probably the correct thing to use. This
+variable contains a L<Coro::Signal> that is broadcats after every server
+tick. Calling C<< ->wait >> on it will suspend the caller until after the
+next server tick.
