This year, Daylight Saving Time (DST) starts three weeks earlier (March 11) and ends one week later (November 4) than in previous years. The below outlines what effect these changes have to T3main.

• If using T3main with a Tadiran PBX or Telrad PBX, the time is updated automatically from the PBX.

• T3 systems purchased after December 2005, running newer version of Linux, will be updated automatically.

• Older versions of T3main will not update automatically. If you are not sure what version you are running, or if you wish to upgrade your system so the time is updated automatically, please contact your dealer.
