Hi all,

Humm, I feel as I have to answer this one. I implemented time on the
axis a few months ago but didn't yet show and example... despite Rene's
pressures... and despite the fact I'm using it every day... shame on me
!

I will do it before middle of next week, since this needs some
explanations.

Nevertheless, I feel that there are many different needs for time on the
axis. Some people need TDatime, others TSDatime, with second precision
or less, and some others, like myself, need a sub-second precision
(typically 10-5 s).
I don't think all these needs are in contradiction, i.e. we should be
able to have only one class handling all this. More would just make
confusion.

I'll try to make the example and specify what are the limitations we
have for the time being.

Cheers

Damir
