- sudden changes in the system time, in order to keep timers
- (including <c><![CDATA[receive-after]]></c>) working. Instead, the time
- maintained by <c><![CDATA[erlang:now/0]]></c> is slowly adjusted towards
- the new system time. (Slowly means in one percent adjustments;
- if the time is off by one minute, the time will be adjusted
- in 100 minutes.)</p>

- will not take place. Instead <c><![CDATA[erlang:now/0]]></c> will always

- on <c><![CDATA[erlang:now/0]]></c>. If the system time jumps, timers
- then time out at the wrong time.</p>
