Code:

miguel@quadbit:~$ date -d "12/01/1964"

miguel@quadbit:~$ date -d "12/01/1965"

never mind, it is a bug on timezone files distributed by canonical for 10.04, for Brasil. Using UTC, the date is displayed just fine....

Code:

miguel@quadbit:~$ env LANG=C date -u -d "Dec 1 1965"
Wed Dec  1 00:00:00 UTC 1965
