From a8325483adb8d9ffda62d3f4900cf52bde70ff62 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Wed, 11 Jun 2014 18:48:11 -0700 Subject: altoslib: Use GPS seconds as an additional sort key for TeleGPS eeprom Long idle periods with TeleGPS can easily overflow 16 bits of tick count. Using the GPS seconds provides an additional sort which will span the tick wrap-around.
