The GPS week number rollover is a phenomenon that happens every 1,024 weeks, which is about 19.6 years. ... This problem was due to an overflow on the GPS epoch.
Many computer systems measure time and date using Unix time, an international standard for digital timekeeping.Unix time is defined as the number of seconds elapsed since 00:00:00 UTC on 1 January 1970 (an arbitrarily chosen time based on the creation of the first Unix system), which has been dubbed the Unix epoch.
GPS dates are expressed as a week number and a day-of-week number, with the week number initially using a ten-bit value and modernised GPS navigation messages using a 13-bit field. Ten-bit systems would roll over every 1024 weeks (about 19.6 years) after Sunday 6 January 1980 (the GPS epoch), and 13-bit systems roll over every 8192 weeks ...
Since rollover occurs every 1,024 GPS weeks (approximately every 19.6 years; 1,024 is 2 10), a receiver that computes current calendar dates needs to deduce the upper week number bits or obtain them from a different source. One possible method is for the receiver to save its current date in memory when shut down, and when powered on, assume ...
Qualcomm BREW, GPS, ATSC 32-bit time stamps: GPS counts weeks (a week is defined to start on Sunday) and 6 January is the first Sunday of 1980. [35] [36] Weeks are stored in a 10-bit integer, and the first GPS week number rollover occurred in August 1999. 31 December 1989: Garmin FIT Epoch. [37]

Negative values, on systems that support them, indicate times before the Unix epoch, with the value decreasing by 1 for every non-leap second before the epoch. For example, 00:00:00 UTC on 1 January 1969 is represented in Unix time as −31 536 000. Every day in Unix time consists of exactly 86 400 seconds.
