The Iridium Re-Epoch

March 3rd 2015 18:00:00 UTC

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 to the new Iridium epoch time manually by the user. 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.

Reprogramming Instructions.

Iridium 9555 and Iridium Extreme® customers can restore the correct time settings by following these steps:
1 Dial *#99#2014051114235500#
2 Press the green key
3 Turn off the phone...wait 60 seconds then turn on the phone

Iridium 9500, 9505 and 9505A customers will need to set the updated time and date from their phone menu. The extended phone set‐up menu must be set to "On” (see page 137 of Iridium 9505A user guide, page 149 of the Iridium 9500 user guide, or page 139 of the Iridium 9505 user guide), then follow these instructions to set time and date:
