Summary:                    Daylight Saving Time (DST) doesn't end at the
correct time for the US
Description: 
There are new rules in 2007 for Daylight Saving Time.

Daylight Saving Time for 2007 beings at 2AM on 3/11, and ends at 2AM on
11/4.

uClibc will start DST at the correct date/time; but it will not end at the
correct time.

The following test case illustrates the bug:

# date -u -s 031109592007 ; date ; sleep 70 ; date
Sun Mar 11 09:59:00 UTC 2007
Sun Mar 11 01:59:00 PST 2007
Sun Mar 11 03:00:10 PDT 2007  <---- GOOD: jumps an hour ahead

# date -u -s 110409592007 ; date ; sleep 70 ; date
Sun Nov  4 09:59:00 UTC 2007
Sun Nov  4 01:59:00 PST 2007
Sun Nov  4 02:00:10 PST 2007  <----- BAD: it should be 1:00:10 !!!

Interestingly, the error occurs only when setting the date with -u:

export TZ="PST8PDT"; date -s 110401592007; date; sleep 70; date
Sun Nov  4 01:59:00 PDT 2007
Sun Nov  4 01:59:00 PDT 2007
Sun Nov  4 01:00:10 PST 2007

The short TZ form was used to show that the new rules are in effect.
