+* SPECIAL NOTE ON TIME
+ Those using SIP phones should be aware the Asterisk is sensitive to large
+jumps in time. Those who live in areas that are on Daylight Savings Time (or
+equivalent) should set their system and hardware clocks to use UTC in order
+to avoid any possible jumps in system time. There should be no noticeable
+effects to the user, as you should still set your system to use the local
+offset from UTC.
+ Even for those who don't live in DST zones, this issue may manifest itself
+if the administrator makes large manual time adjustments. Thus, it is good
+practice to keep the time on your Asterisk server synced to a reliable
+source, such as an NTP server.
+ Also note that this issue is separate from the clocking of TDM channels, and
+is known to at least affect SIP registrations.
