Changes in release 2.1
+ [2.0.12]
+* date -d 'last friday' print a date/time that was one hour off
+ (e.g., 23:00 on *thursday* rather than 00:00 of the preceding friday)
+ when run such that the current time and the target date/time fall on
+ opposite sides of a daylight savings time transition.
+ This problem arises only with relative date strings like `last monday'.
+ It is not a problem with strings that include absolute dates.
[2.0.11]
* setting the date now works properly, even when using -u
* `date -f - < /dev/null' no longer dumps core
