Use ls -lrt /var/sadm/system/logs look for begin.log_xxxxxx or finish.log_xxxxxxx


ls -lrt

total 799

lrwxrwxrwx 1 root root 20 Nov 15 2006 begin.log -> begin.log_2006_11_15
-rw-r--r-- 1 root root 90 Nov 15 2006 begin.log_2006_11_15
lrwxrwxrwx 1 root root 21 Nov 15 2006 finish.log -> finish.log_2006_11_15

The symfile name and the timestamp both match the date installed.
