[OS X TeX] Re: draftcopy "weirdness"

[Claus Gerhardt]

I wonder how I could get the code wrong years ago or ifthenelse is treating "<" as "≤"; of course it should read

\ifthenelse{\value{minutes}<10}{\thehours :0\theminutes}{\thehours:\theminutes}}

Anyone who wants a trailing 0 in front a single digit hour has to do it himself.

There is an example in The LaTeX Companion 2nd ed (TLC2) Example A.3.2  page 871, on how to  turn this into an hour : Minutes representation; this code is between the rows of %%%%%% below, I only changed their `h' and `min' to a colon `:'; you can modify this to other representations. I think that there is also a datetime package which would do this and probably more.

>>> That's very nice.  I like it.  In fact, I saved your code into a file named "vamosdraft.sty". :-)  My only further question is how can I get the time to print in four digits, viz., "hh:mm"?  Now, if the time is 6:04, e.g., it prints 6:4.  See
