        All platforms, FreeBSD STABLE, date(1) command
>Description:
        The date(1) command does not properly deal with crossing
standard-daylight time boundaries. The _current_ daylight setting is
used rather than the one for the time the user provides. For example,
the switch to daylight time for my timezone (Pacific US) happened on
the morning of April 1st this year,

        $ date -j 200104010000
        Sat Mar 31 23:00:00 PST 2001
        $ date -j 200104020000
        Mon Apr  2 00:00:00 PDT 2001

As shown, when I want date to print the time for Sun Apr  1 00:00:00
PST 2001, it actually prints the time from an hour earlier. This is
not what the user would expect. Why should the current daylight
setting affect anything?

>How-To-Repeat:
        See above example.
>Fix:
        The date(1) command should let mktime(3) figure out the
daylight setting for the time it is given rather than using the
current daylight setting.
