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 (13:00:00 ET). After the re-epoch, the time and date on your phone’s handset display will revert back to December 29, 2007 , 7:26:29 UTC. The date and time will progress from there until you manually adjust your phone settings to the new Iridium epoch time. You may reset your phone(s) at any time after March 3, 2015. Iridium GO! devices will handle the time change automatically and do not require reprogramming.
If you need them, here are the reprogramming instructions:

If you have an Iridium 9500, 9505 or 9505A you will need to set the updated time and date from your phone menu.
