UTC and std indicators:

I am trying to write a Common Lisp program to compute local time using
the `tz' database.

I am confused about the use of the UTC/local indicators and the
standard/wall indicators in a tzfile.  According to tzfile(5), they "are
used when a time zone file is used in handling POSIX-style time zone
environment variables".  Does this mean that these indicators are
irrelevant when computing local time using only a tzfile (without
looking at the environment).

I have tried reading `localtime.c' using my negligible knowledge of C,
but haven't understood the role of the indicators.  Any pointers on this
would be most welcome.
