Hi list,
I was wondering if there is a "\time" equivalent similar to "\currentdate" ->
"\date"?
I know from the wiki (and source) that there is "\currenttime", but "\time[h=8, m=30]"
will not typeset "8:30", so it doesn't seem to be implemented. I understand that such an
implementation might become arbitrarily complicated …
In fact, I'm trying to typeset durations like "3:30 min" which is not exactly a
"time" either, but neither \unit{3:30 minute} nor a math formula achieve the expected
rendering. Of course, one could just type it plainly, but maybe this little gap is worthwhile
considering in a future version. :-)
It's no problem to add something and it's kind of trivial to implement
anyway. See attached.
You need to keep in mind that \time is also a primitive (do users
actually use that one?) so we need to remain compatible with its usage
as number, think:
\time1234 % sets the time
\time[] % typesets the time
\the\time % typesets the number
intercepting h and m also has to involve overflow
how about seconds? and pm/am ?
you can test the attached proof of concept and contemplate the above
(and do some research in language dependencies) .. when i got enough
input we can (after wolfgangs quality assurance check) add something to
the core (in order to keep the format small i can then kick out
something unused)
