depending on what you need it do, sophisticated things can be done with an excellent plug-in from x2max.com
which generates images from your data (quite a long learning period).
otherwise you can use the old trick which consists in using '|' characters in arial pt 8, condensed and bold to simulate a horizontal color bar on screen. that does a cheap trick, but for simple time representation, the effect is correct. to calc the bar length, you need to find out how many characters you need for say 1 hour. then you can easily define the field for any duration once you know the ratio in betwen time and amount of character.
see below an example of time bar simulating a gantt chart bar.
in this definition, I define 3 duration + an offset for this afternoon (app requirement)
$aprem is the afternonn offset
$start if the start of the activity to be shown in color (user defined in this case)
$duree = duration
$rest is the rest untill the end of the bar.

then I defined 3 concatenated bars, grey before and after the event, and colored for the event.
to get this example neat, use a text field, 40 pixels wide, times new roman pt9.
Let(
[
$aprem=21600*ma;
$start =Int((time_start - 28800 - $aprem) / 21600 *40) ;
$duree =Int((time_stop - time_start) / 21600 *40);
$rest =  Int ((50400 + $aprem - time_stop)  / 21600* 40) ]
;
Left(TextColor("||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||"; RGB(204;204;204) ) ; $start ) &
Middle (TextColor("||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||"; lieux::colour  ) ; $start ; $duree) & 
Middle (TextColor("||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||"; RGB(204;204;204)  ) ; $start + $duree ; $rest)
)
