Because Ingress is heavily Location dependent,. I thought this might be a good reminder/awareness. It may end up being nothing,. but again, awareness is important.

"The GPS Week Number count began at approximately midnight on the evening of 05 January 1980 / morning of 06 January 1980. Since that time, the count has been incremented by 1 each week, and broadcast as part of the GPS message. The GPS Week Number field is modulo 1024. This means that at the completion of week 1023, the GPS week number rolled over to 0 on midnight GPS Time of the evening of 21 August 1999 / morning of 22 August 1999. Note that this corresponded to 23:59:47 UTC on 21 August 1999."

If you depend on any device that gives you GPS Location (Garmin, BGAN, OnStar, ??).. you may want to look into their Support/Documents and make sure you're OK or planning to do a Software update in the next 4 days or sooner. :)
