The -t option to script gives precise timing of output to the terminal,

tcsh has the feature of printing time automatically after each command
executed (time variable). it also has 'precmd' and 'postcmd' aliases that
are executed (if set) before and after any command executed.
However tcsh is not bourne shell compatible, you'd have to learn working
with it (well, I prefer tcsh over bash)
I used to use tcsh a few years ago (I believe middle to late 90's) when
studying at my local city college and found it quite useful. I remember
defining aliases, and having to remember the difference between 'export
VAR=VALUE' and 'setenv VAR VALUE' in different shell environments.
When bash was released and began to be used in linux I thought it was
better (in some ways I think it is) so I made the switch (on my home
system). Lately I'm spending a lot more time at the shell prompt so
I've noticed the need for minor things like getting the time for
commands, etc. I guess I'm growing in shell experience? :-)
Anyway, it looks like tcsh has a lot more than bash in this area. I may
just give tcsh another try. On the other hand, it's not that
inconvenient to not be able to get this automatically in bash. I would
just have to remember to use the 'time' command when I really want to
time something. :-)
Honestly, though, I'll most probably end up sticking with bash just
because I'm so used to it by now. I really like all the suggestions, I
just thought that someone might know something that I did not and was
not able to figure out. It seems that this is just something that bash
does not support and I sort of understand why. (Like someone already
said, what if the prompt scrolls out of visibility? The usefulness of
printing something just before command execution is hindered.)
In all honestly, this is not something absolutely indispensable for me
just something I thought that if it were possible was something that I
sort of wanted to do. However, it wont make my work harder if I don't
have it.
Thanks for all suggestions everyone.
