Save the date: GPS Week Number Rollover Event – April 6th 2019
If your networks or systems use Coordinated Universal Time (UTC), April 6th 2019 is probably a date worth marking in advance. On, or possibly after, this date, some GPS receivers may start to behave strangely. The data they output may jump backwards in time, resulting in month and year timestamps that are potentially up to 20 years out of date.This is a known issue; in April 2018 the Department of Homeland Security in the United States issued a memo to make GPS users aware of the situation. Any changes, adjustments, or other actions are ultimately the responsibility of the user, so DHS strongly recommends owners and operators of critical infrastructure to prepare for the rollover.This refers to the GPS Week Rollover on Coordinated Universal Time (UTC) derived from GPS devices.
