I recently saw this blog post regarding performance when the TZ environment
variable is not set:

I have noticed this problem when stracing running daemons on my systems and
would like to fix it. I reviewed the official Ubuntu documentation for where to
define environment variables:

I tried defining TZ in /etc/environment and in /etc/profile.d/, but I
cannot get this environment variable to be available in all cases (e.g. if I
just execute bash without --login or if I run the sample c program provided in
the above article). How can I make the TZ environment variable defined
completely system-wide?
