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. + * MORE INFORMATION See the doc directory for more documentation. |
