	FreeBSD 4.4-stable

>Description:

Default newsyslog.conf includes the following line:

/var/log/maillog                        644  7     *    @T00  Z

When the local region enters daylight savings time, the first day
does not have the first hour, so such hour is invalid.

I suppose a similar problem will happen at daylight savings end.

>How-To-Repeat:

Simulate a first day of a daylight savings station, and run newsyslog.

>Fix:

Options:

- Fix newsyslog to detect daylight savings start/end.

- Fix mktime(3) to return a specific error for daylight savings
  time inexistence.

- As a simple and dirty workaround, just change newsyslog.conf.  ;-)

Sorry no patches.
