nginx 0.7.14 *) Change: now the ssl_certificate and ssl_certificate_key directives have not default values. *) Feature: the "listen" directive supports the "ssl" parameter. *) Feature: now nginx takes into account a time zone change while reconfiguration on FreeBSD and Linux. *) Bugfix: the "listen" directive parameters such as "backlog", "rcvbuf", etc. were not set, if a default server was not the first one. *) Bugfix: if URI part captured by a "rewrite" directive was used as a query string, then the query string was not escaped. *) Bugfix: configuration file validity test improvements.

+ * by calling tzset() with TZ and then without TZ to update timezone.
+ * The trick should work since FreeBSD 2.1.0.
+ *
+ * Linux does not test /etc/localtime change in localtime(),
+ * but may stat("/etc/localtime") several times in every strftime(),
+ * therefore we use it to update timezone.
+ *
+ * Solaris does not test /etc/TIMEZONE change too and no workaround available.
