+
+A struct with the following items:
+
+=over
+
+=item C<db_time>
+
+C<dateTime> The current time in Bugzilla's B<local time zone>, according 
+to the Bugzilla I<database server>.
+
+Note that Bugzilla assumes that the database and the webserver are running
+in the same time zone. However, if the web server and the database server
+aren't synchronized for some reason, I<this> is the time that you should
+rely on for doing searches and other input to the WebService.
+
+=item C<web_time>
+
+C<dateTime> This is the current time in Bugzilla's B<local time zone>, 
+according to Bugzilla's I<web server>.
+
+This might be different by a second from C<db_time> since this comes from
+a different source. If it's any more different than a second, then there is
+likely some problem with this Bugzilla instance. In this case you should
+rely on the C<db_time>, not the C<web_time>.
+
+=item C<web_time_utc>
+
+The same as C<web_time>, but in the B<UTC> time zone instead of the local
+time zone.
+
+=item C<tz_name>
+
+C<string> The long name of the time zone that the Bugzilla web server is 
+in. Will usually look something like: C<America/Los Angeles>
+
+=item C<tz_short_name>
+
+C<string> The "short name" of the time zone that the Bugzilla web server
+is in. This should only be used for display, and not relied on for your
+programs, because different time zones can have the same short name.
+(For example, there are two C<EST>s.)
+
+This will look something like: C<PST>.
+
+=item C<tz_offset>
+
+C<string> The timezone offset as a string in (+/-)XXXX (RFC 2822) format.
