Tiger vs Leopard sysctl kern difference

Scripting Forums AppleScript | Mac OS X
#1

In Tiger this gives me the date of the last time the computer was rebooted:

do shell script “sysctl kern.boottime | awk ‘{print $5,$4,$7,$6}’”
Result: “2 Oct 2008 16:36:35”

The same line executed in Leopard gives me:
“1223056229, = = usec”

Anyone seen this difference yet?

#2

OK, I figured out how to make it work.

do shell script “sysctl kern.boottime | awk ‘{print $12,$11,$14,$13}’”

Has anyone seen other example of different results from basic unix commands like this?
