I want to apply this patch, but I am confused about the comment you added
in the patch:
+ // This formatter uses local timezone, not GMT.
This seems contradictory. Isn't the issue that svn log --xml outputs
dates in GMT, and that is what is passed to the method. Therefore, we
need to tell date formatter that it is getting a date in GMT timezone? If
so, shouldn't the comment say the opposite, that the formatter expects
GMT?
