posted in gentoo form and got this answer!
        Works here with /etc/localtime pointing to
        /usr/share/zoneinfo/Europe/Berlin and an unset TZ variable. But:

        # LC_ALL=C TZ=/usr/share/zoneinfo/Europe/Amsterdam date --date 
"19370701"
        Wed Jun 30 23:59:32 NST 1937

        I guessed your timezone from your mail address.

        Time warp? Temporal discontinuity? Leap seconds?

        Probably the time in the Netherlands was adjusted from one standard to
        another standard in 1937.

        Googling for "Europe/Amsterdam 1937" gives e.g.
        <http://nssdcftp.gsfc.nasa.gov/usr/share/lib/zoneinfo/europe>,
        which has:

        # Zone  NAME            GMTOFF  RULES   FORMAT  [UNTIL]
        Zone Europe/Amsterdam   0:19:28 -       LMT     1892 May
