The value has the form @code{(@var{offset} @var{name})}. Here
-@var{offset} is an integer giving the number of seconds ahead of UTC
+@var{offset} is an integer giving the number of seconds ahead of Universal Time
(east of Greenwich). A negative value means west of Greenwich. The
second element, @var{name}, is a string giving the name of the time
zone. Both elements change when daylight saving time begins or ends;
@vindex TZ, environment variable
The default time zone is determined by the @env{TZ} environment
variable. @xref{System Environment}. For example, you can tell Emacs
-to default to universal time with @code{(setenv "TZ" "UTC0")}. If
+to default to Universal Time with @code{(setenv "TZ" "UTC0")}. If
@env{TZ} is not in the environment, Emacs uses system wall clock time,
which is a platform-dependent default time zone.
Many 32-bit operating systems are limited to system times containing
32 bits of information in their seconds component; these systems

systems have larger seconds components, and can represent times far in
the past or future.

Manual}) to do most of the work. In order to communicate with that
