Andur Sunrider leaves H'ratth for Ambria in 3999 BBY per. Thesays that 2 years prior (4001 BBY), Andur went to H'ratth, and six years prior to that (4007 BBY), he saw the Force ghost of his grandfather Jev, who the Companion says disappeared on a mission a year prior to that (4008 BBY). If you start at 3999 and count back the number of years (2, then 6, then 1) you arrive at 4008 BBY, which has to be the year of Jev's death, given that he appeared to Andur in ghost form a year later (4007 BBY).
