See also the libc documentation.  The behavior is implemented in
libc.  The docs are available online at:

  
https://www.gnu.org/software/libc/manual/html_node/TZ-Variable.html#TZ-Variable

The online standards docs:

  http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap08.html

And additionally the FAQ:

If you have the glibc documentation installed then you can browse the
locally installed docs.  This is in the glibc-doc package on your
Ubuntu system.

  $ info libc 'TZ Variable'
