Consulting the log file for ChangeLog (or any fast moving file, maybe 
version.c) and getting the full date is as trivial as examining said 
log for the tag that was merged in.  If one writes it down instead of 
consulting the log file, one can just as easily write down the full 
date (of course, using Z or GMT time).  Anybody that does this be 
memory, well, they have a really good memory and surely the full date 
isn't any more difficult for them.

Also, dated merges from named branches works just fine.  What doesn't 
work is that the main branch (mainline) doesn't have a name, so no 
merging from it.(?)

The above comments only relate to the -j option, for other options, the 
combo doesn't work.  :-(
