I'm on Solaris x86  10 & 11.

Q1:
What's the right way to disable tcp_timestamp?

http://www.cns.nyu.edu/~fan/sun-docs/sol10-01-13/html/E37386/chapter4-31.html
Above link does not have any parameters for tcp_timestamps (guess there is an 's' at
the back) & the closest is tcp_tstamp_always

Q2:
At some other URLs, it gave the same method as setting it in RHEL ie
   echo 0 > /proc/sys/net/ipv4/tcp_timestamps     &
add line below to etc/sysctl.conf (create the file if it does not already exist):
   net.ipv4.tcp_timestamps = 0

Q3:
if sysctl.conf does not exist, is that the only line to add in or we ought to
add a few other lines to make the parameters "balanced".  I recall I used
to tweak /etc/system & several parameters need to be inside this system file
