duration without hours?

duration without hours?

I have a silly table I am planning to use to teach myself a little bit
about R; it contains durations measured in minutes and seconds:

#+TBLFM: $2=vmean(@2..@-1);T::$3=vmean(@2..@-1);T::$4=vmean($2..$-1);T

I have a bunch of questions but will start with what is maybe the most
basic: can I write durations in minutes and seconds only? the extra 00: is
sort of annoying to type when I am tired.

Later I'll want to think about the best way to turn this data into a plot
of fastest, slowest, and mean times day-to-day. But not tonight, I'm beat!
Thanks,
Matt

I'd recommend using org-capture to add to the table, and use a simple
function to take input in the form of "2h4m3s" and convert that to
"02:04:03".  Much faster to type.  :)

Just to be contrary, for those of us who clock our working time with
orgmode and are not interested in know exactly how many seconds we spend
at the office, it would be nice to have durations expressed in hours and
minutes only.  Maybe there could be something like the alignment setting
for columns which would affect the formatting.

Cheers,
