keeping track of time.

[oracle nine <oracle nine gmail com>]

Hi. Im new to gtk and the list.

I am writing billiards management program under gtk2 on Linux. Each 
billiards table is represented by a widget that will toggle the table 
open or closed. While a table is open, I want to insert a label that 
displays how much time has elapsed.

I want the application to be aware of clock ticks with are resolution of 
1 second.  How could I implement this functionality efficiently. Would 
it be best to create an interval timer (itimer) every second? Or is 
there a gtk handler for time that would be better suited to this task. 
gtk_main () is essentially a message queue. Searches have yielded few 
results that make sense to me. And a few people have told me that gtk 
timers are less accurate.

Any help would be appreciated.

thanks.
