Iridium have updated the system time on their satellites as of 3rd March 2015. Iridium call this a "re-epoch". Since that point, some Iridium handsets, including the Iridium 9555, Iridium 9575 Extreme, Iridium 9505a and Iridium 9500) will display an incorrect system time (of 2008) until the user corrects the time by entering in a sequence of numbers on the handset. (Note, Iridium-Go is unaffected)
Note that this change should have no effect on the ability to make phone calls, send SMS messages or to make internet data calls. However, the time shown on the handset display will be reset to start counting from late 2007 and as you read this post will be showing a date in 2008 (or perhaps 2009 if you are reading this in 2016!). Additionally the Iridium 9575 GPS will fail to obtain a valid position and hence the Iridium 9575 tracking feature will stop working until the system time is reset as below.
How to reset the System Time on your Iridium 9555 or 9575 Extreme
