As part of standard satellite network operations, Iridium periodically resets the Iridium system time count, in a process known as a “re-epoch”. It consists of a one-time adjustment in Iridium time. Iridium plans to reset the system time on March 3rd, 2015 at 18:00:00 UTC.
For Iridium satellite phone users, this epoch change on March 3rd, 2015 will have no impact on service availability and the ability to successfully complete phone calls, SMS messages, or data services.
However, the appearance of the time and date will revert back to December 29, 2007 , 7:26:29 UTC on the handset display and will progress on this baseline until phone settings are adjusted manually by the user to the new Iridium epoch time. The user can reset their phone at any time after March 3, 2015. Iridium GO! devices will handle the time change automatically and do not require reprogramming.
