It's not a bug.  At least not according to the ISO C standard.  See 
http://www.opengroup.org/onlinepubs/007904975/basedefs/xbd_chap04.html#tag_04_14 
for the definition of 'Seconds Since the Epoch', then cross-reference to the 
man page of mktime.

I don't like it any more than you do, but that is the letter of the standard.  

Thomas, any comments?

Our implementation is broken, then.  Thomas, is this fixable for a 7.2.x 
release, or something for 7.3?
